Question

Which equation can you use to solve for X?

O X+56 = 180
O x + 56 = 146
X + 146 = 180
O 180 - 1 = 146
56°
146°​

Answer 1

I think the second option is correct.

because the unknown angle is 90.

and if replace anyone of the x with 90 the equation isn't correct except with the second option.

Explanation:

if you want me to show you how I got 90 degree for x just tell me and I'll show you

Hope this helps
