Question

Can someone help? I don’t know the equation to use and how to solve. Thank you!! Anything will helps!

Answer 1

`x=55\\`

Explanation:

this is because the angles in a right angle should add up to 90

x is simplified to 2x and 20 is added to both sides

2x = 110

divide by 2 on both sides answer is 55

double check by doing the inverse
