Sure! Here are the answers to each of your questions:

  1. Third Angle in a Right Triangle: In a right triangle, the sum of the angles is always 180°. Since one angle is 90°, and another is 65°, the third angle can be calculated as follows: \[ 180° - 90° - 65° = 25° \] Answer: 25°

  2. Measure of Exterior Angle \( x \): The sum of the angles in a triangle is also 180°. Given that the two known angles are 37° and 42°, we can find the third angle \( x \): \[ 37° + 42° + x = 180° \] \[ x = 180° - 37° - 42° = 101° \] Answer: 101°

  3. Corresponding Angles: Since lines S and T are parallel and an angle of 22° is formed at the intersection with the transversal, the corresponding angles formed at the other intersection (angles 5, 6, 7) will also be equal to 22°. Answer: 5, 7, 6

  4. Relationship of the Sides in Triangle \( \Delta MNO \) based on the Pythagorean Theorem: The Pythagorean Theorem states that for a right triangle: \[ a^2 + b^2 = c^2 \] If we consider the sides \( m \) and \( n \) to be the legs, and the hypotenuse as \( c \): Answer: \( m^2 + n^2 = c^2 \)

  5. Is the triangle with sides 60, 75, and 45 a right triangle?: We check using the Pythagorean Theorem:

    • \( 60^2 + 45^2 = 3600 + 2025 = 5625 \)
    • \( 75^2 = 5625 \) Since \( 60^2 + 45^2 = 75^2 \), it is a right triangle. Answer: Yes, because 5,625 equals 5,625.
  6. Is triangle DEF with sides 50, 40, and 32 a right triangle?: We check:

    • \( 50^2 = 2500 \)
    • \( 40^2 + 32^2 = 1600 + 1024 = 2624 \) (not equal)
    • Check the largest triangle side to see: \( 50^2 = 40^2 + 32^2 \) Therefore, the triangle is NOT a right triangle. Answer: 0
  7. Length of the Hypotenuse: For a triangle with legs 12 and 16, we use: \[ c = \sqrt{12^2 + 16^2} = \sqrt{144 + 256} = \sqrt{400} = 20 \] Answer: 20

  8. Length of the Other Leg when one leg is 12 and the hypotenuse is 16: \[ a^2 + 12^2 = 16^2 \] \[ a^2 + 144 = 256 \] \[ a^2 = 256 - 144 = 112 \] \[ a = \sqrt{112} \approx 10.583 \] Rounded to the nearest tenth: Answer: 10.6

  9. Distance for the throw from the shortstop to first base: The horizontal distance (base path) is 90 feet, and she is 30 feet from second base. We can visualize this as a right triangle: \[ d = \sqrt{(90)^2 + (30)^2} = \sqrt{8100 + 900} = \sqrt{9000} \approx 94.87 \] Rounding to the nearest tenth: Answer: 94.9 feet

  10. Length between the two points using the Pythagorean Theorem: For points (3,2) and (7,8), calculate: \[ \text{Length} = \sqrt{(7-3)^2 + (8-2)^2} = \sqrt{4^2 + 6^2} = \sqrt{16 + 36} = \sqrt{52} \approx 7.21 \] Rounded to the nearest hundredth: Answer: 7.21

The length of the coffee table will be 44 in., the width 24 in., and the height 14 in. Find the length Keysha should make each diagonal. Round the answer to the nearest tenth.(1 point)
in.

Let’s find the answers to each of your new questions:

11. Slant Height of the Square Pyramid:

For a square pyramid, the slant height can be found using the height of the pyramid and half the length of the base. The formula can be expressed as:

\[ \text{slant height} = \sqrt{h^2 + \left(\frac{b}{2}\right)^2} \]

where \(h\) is the height (15 feet) and \(b\) is the base edge length (16 feet).

Calculating:

\[ \text{slant height} = \sqrt{15^2 + \left(\frac{16}{2}\right)^2} = \sqrt{15^2 + 8^2} = \sqrt{225 + 64} = \sqrt{289} = 17 \text{ ft} \]

Answer: 17 ft

12. Length of the Diagonal of the Prism:

To find the length of the diagonal in a rectangular prism, we can use the formula:

\[ d = \sqrt{l^2 + w^2 + h^2} \]

where \(l\) is the length (4 cm), \(w\) is the width (3 cm), and \(h\) is the height (12 cm).

Calculating:

\[ d = \sqrt{4^2 + 3^2 + 12^2} = \sqrt{16 + 9 + 144} = \sqrt{169} = 13 \text{ cm} \]

Answer: 13 cm

13. Height of the Great Pyramid of Giza:

To find the height of the pyramid, we can use the relationship between the slant height, height, and half the base length. The formula is:

\[ s^2 = h^2 + \left(\frac{b}{2}\right)^2 \]

where \(s\) is the slant height (180.2 m), \(b\) is the base edge length (230.5 m), and \(h\) is the height we want to find.

Calculating:

\[ h^2 = s^2 - \left(\frac{b}{2}\right)^2 \]

First, calculate \( \frac{b}{2} \):

\[ \frac{b}{2} = \frac{230.5}{2} = 115.25 \text{ m} \]

Now substituting:

\[ h^2 = 180.2^2 - 115.25^2 = 32472.04 - 13273.0625 = 19198.9775 \] \[ h = \sqrt{19198.9775} \approx 138.645 \] Rounding to the nearest tenth:

Answer: 138.6 m

14. Length of Each Diagonal of the Coffee Table:

To find the diagonal of a rectangular prism (which in this case is the coffee table), we use the same formula as above:

\[ d = \sqrt{l^2 + w^2 + h^2} \]

Here, the dimensions are: length \(l = 44\) in, width \(w = 24\) in, and height \(h = 14\) in.

Calculating:

\[ d = \sqrt{44^2 + 24^2 + 14^2} = \sqrt{1936 + 576 + 196} = \sqrt{2708} \approx 52.0 \text{ in} \]

Rounding to the nearest tenth:

Answer: 52.0 in

Thank you for your responses! Let’s review your answers to ensure they are accurate and consistent with the calculations:

Question Review

  1. Measure of angle \( x \): You had an initial answer of 101° calculated based on the given angles in a triangle (37° + 42°). If your new answer is 79°, it doesn't seem mathematically justified in this context. Please check the setup of the angle relationships.

  2. Corresponding Angles: You provided the angles 2, 3, 6. If angle 2 is directly corresponding to angle 22° when the lines are parallel, then that is accurate. The previously calculated answer of 5, 7, 6 would depend on their spatial relationship. Please double-check the diagram for confirmation.

  3. Pythagorean Theorem Setup: If your answer for the relationship of the sides in the triangle is \( o^2 \), that means you're referring to the sides of a triangle where \( o \) represents the length of one of the sides. This means the relationship should be set up as \( m^2 + n^2 = o^2 \) where \( o \) is the hypotenuse.

  4. Height of the Great Pyramid of Giza: You indicated 138.5 m as the height. According to the prior calculation, the height derived was approximately 138.6 m, but rounding can vary slightly. However, if you are rounding differently, both could be considered correct depending on the rounding convention.
