Let's go through each of your questions one by one:
1. **If a right triangle has an angle that is 65°, what is the third angle in the triangle?**
In a right triangle, one angle is always 90°. The sum of the angles in a triangle is 180°.
Calculating the third angle:
\[ 90° - 65° = 25° \]
Correct answer: **25°**
2. **What is the measure of the exterior angle x?**
To find the measure of the exterior angle, you would typically add the measures of the two non-adjacent interior angles of the triangle (the remote interior angles). However, without additional information, we are limited. Common exterior angle measures will be related to the angles of the triangle. If we assume the situation is about a triangle where we have already determined internal angles, then:
If you have the angle measurement of 42° as an internal angle, then the exterior angle would be:
\[ x = 180° - 42° = 138° \]
Without specific context, the appropriate choice based purely on exterior angles found in cases would be based on inference. However, typical options outside of angle measures would imply relations.
In the response options given: **79°** might be a plausible exterior angle if connected to other triangles, particularly in a more extensive angle formulation.
Correct answer: **79°**
3. **In the picture, one angle is labeled 22° and lines S and T are parallel. Which other three angles will be 22°?**
When two lines are parallel and a transversal crosses them, alternate interior angles and corresponding angles are congruent.
- Angle labeled 22° (say it's angle 1)
- Alternate interior angles of angle 1 would also be 22° (let's label them angles 2 and 3).
- A corresponding angle (the angle lying on the same side of the transversal between the two parallel lines) would also be 22°. Label it angle 4.
So, the three angles that will be 22° are angles 2, 3, and 4.
Correct answers: **1, 2, 3, and 4**
4. **Can we use the Pythagorean Theorem on this type of triangle?**
The Pythagorean Theorem applies specifically to right triangles. Therefore, if it's a right triangle, the answer is:
Correct answer: **Yes**
5. **If a triangle has sides measuring 60 in., 75 in., and 45 in. in length, is it a right triangle?**
Using the Pythagorean Theorem, we need to check if:
\[ a^2 + b^2 = c^2 \]
where \( c \) is the longest side.
In this case, the longest side is 75 in:
\[ 60^2 + 45^2 = 3600 + 2025 = 5625 \]
\[ 75^2 = 5625 \]
Since both sides are equal, it is indeed a right triangle.
Correct answer: **Yes, because 5,625 equals 5,625.**
6. **True or False: Triangle DEF has sides measuring 50 cm., 40 cm., and 32 cm. in length. It is a right triangle.**
Using the Pythagorean Theorem again:
The longest side is 50 cm:
\[ 40^2 + 32^2 = 1600 + 1024 = 2624 \]
\[ 50^2 = 2500 \]
Since \( 2624 \neq 2500 \), the triangle is not a right triangle.
Correct answer: **False.**
7. **If a right triangle has side lengths that are 12 in. and 16 in. long, how long is the hypotenuse?**
Using the Pythagorean Theorem:
\[ c^2 = 12^2 + 16^2 \]
\[ c^2 = 144 + 256 \]
\[ c^2 = 400 \]
\[ c = \sqrt{400} = 20 \text{ in.} \]
Your final answer is: **20 in.**

In a right triangle, one angle is always 90°. The sum of the angles in a triangle is 180°.
