I need help please. hdjdkxkdmmzmckdkkci

Step-by-step explanation:

Plug in each number:

For A. you will do this: 2*78 + 6 = 156 + 6 = 162. So, no. You need 90 degrees.

For B. you will do this: 2*72 + 6 = 144 + 6 = 150. So, no. You need 90 degrees.

For C. you will do this: 2*42 + 6 = 84 + 6 = 90. This is a possible answer choice, but you should keep going just in case.

For D. you will do this: 2*36 + 6 = 72 + 6 = 78. So, no because you need 90 degrees for a right angle. (A right angle is 90 degrees)

Hope this helps! :)
