Question

Find the value of x.





Answer 80
69
31
21

Answer 1

x = 21

Answer 2

According to the remote interior angles theorem, the two inside angles of a triangle add up to the exterior angle (that the interior angles don't touch)

so that means

(interior angle1) + (interior angle2) = 100

(2x+27) + (2x - 11) = 100

2x+27 + 2x - 11 = 100

4x+16 = 100

4x = 100-16

4x = 84

x = 84/4

x = 21
