Question

I am an angle in a triangle. My measure is 90 degrees. What am I? what angle is this

Answer 1

An angle in a triangle with a measure of 90 degrees is called a right angle.

Answer 2

The angle measures of a triangle are shown in the diagram.
What is the value of x?

2 points
A. 55
B. 21
C. 11
D. 28
(5x)degrees (4x+7)degrees

Answer 3

To find the value of x, we need to use the fact that the sum of the angle measures in a triangle is always 180 degrees.

Since we have two angle measures given, we can set up an equation:

(5x) + (4x + 7) + 90 = 180

Combine like terms:

9x + 7 + 90 = 180

Simplify:

9x + 97 = 180

Subtract 97 from both sides:

9x = 83

Now, divide both sides by 9 to solve for x:

x = 83/9

Using a calculator, we find that x ≈ 9.22.

Therefore, none of the given options A, B, C, or D is the correct answer for the value of x.
