Question

Part a: Which relationship describes <1 and <2?

Part b: What is the value of x?

Part c: What is the m22?

Answer 1

x = 8

Explanation:

Part a: <1 and <2 are alternate exterior angles because line horizontal lines are parallel

Part b: the value of x can be calculated with the following equation

7x + 15 = 10x - 9 because alternate angles has same measure

15 + 9 = 10x - 7x

24 = 3x divide both sides by 3

8 = x
