These angles are vertical angles meaning that they are equal to each other. Here is the equation for this problem:
x + 40 = 3x
Combine like terms
(x-x) + 40 = 3x - x
40 = 2x
Isolate x
40/2 = 2x/2
x = 20
Hope this helped!
Add 7 to both sides
At the left hand side 7 will cancel 7
At the right hand side 7 will add up
Divide through by 2
simplify the fraction
