Step-by-step explanation:
All of the angles in a triangle add up to 180. Since we know that the box in the left corner is 90° because it is a right angle then we just need to find x
2x+90=180
subtract 90
2x=90
divide by 2
x=45
Hope that helps :)
Answer:
The two xs are contained in the same triangle.
Every triangle has 180 degrees.
2*x + 90 = 180 Subtract 90 from each side
2x +90 - 90 = 180 - 90
2x = 90 Divide by 2
2x/2 = 90/2
x = 45
