Question

Find the value of the lettered angles in these diagram​

Answer 1

1. m = 65°

x = 30°

2. x = 40°

Explanation:

1. Since the figure is an isosceles triangle, m = 2x - 5

180 - 50 = 130 (Total degree for both m and 2x - 5)

130 ÷ 2 = 65 (m and 2x - 5 angle degrees)

65 - 5 = 60 (2x)

2 x = 60°

x = 60 ÷ 2 = 30°

2. I forgot the parallel rule for question 2, but I think X and 40° is parallel to each other?
