Question

Find the measure of x​

Answer 1

X= 130°. The line from 110 and it’s outside angle is 180, so 180-110 = 70. And 70 + 160 = 230. Since all the outer angles equal 360 you can take 360-230 and get your answer of 130

Answer 2

x = 130 degrees

Explanation:

ok so first find all the interior angles of the triangle before using the supplementary angle rule to find x.

the interior angle A = 20 degrees, so the interior angle B must be 50 degrees (since there can only be 180 degrees in a triangle). So, since B is 50 degrees and x is 180-50, we know that x = 130 degrees
