Question

Find the missing angles: you may have to find missing angles that are not labeled.

Answer 1

Explanation:

f = 50 (parallel lines)

180 - 50 = a (angle sum of straight line)

a = 130

50 + 75 + b = 180 (angle sum of triangle)

125 + b = 180

b = 180 - 125

= 55

c = 55 (vertically opposite angles)

e = 55 (alternate angles)

d= 180 - 55 (angle sum of straight line)

= 125

Answer 2

b= 55
angle b +50+75 = 180 ( sum of angles in a triangle )
b= 180-50-75 =55

b= c = 55 ( vertically opposite angles )

d= 125
d= 125 - b ( supplementary angles
d= 180 - 55 = 125
