Question

Two lines intersect to form angles 1, 2, 3, and 4 as given. The measure of ∠1 is 43°. What is the measure of ​∠4​ ? pls helppp

Answer 1

137

Explanation:

180-43=137

the 180 comes from when you combine angles 1 and 2 (because they form a straight line). you subtract angle 1 and you will get angle 2. since angle 2 and 4 are across from each other, that means they are the same degree. so the answer would be 137
