Question

Can anyone please solve x for both 7a and 7b please, as soon as possible. thanks :,)

Answer 1

7a. x = 8

7b. x = 20

Explanation:

Here's my work. For 7a, both equations add up to 90 degrees, because there is the right angle marking between both of them.

For 7b, the angles are supplementary, or add up 180, because a straight line = 180. Hope this helps :)
