Both angles are equal to 140 so add them and make them equal to each other.
40+2x=140
then solve for x.
2x = 100
X=40
Answer:
x = 50
Step-by-step explanation:
I subtracted 140 - 40 to get a 100
Then I did 100/2 which is 50

Using Pathogorean Theorem.....
40 = the square root of 24^2 + 32^2
40 = the square root of 576 + 1024
40 = the square root of 1600
40 = 40
