Question

How do you work out the size of angle x ?

Answer 1

Answer:

117°

Step-by-step explanation:

Angle of straight line is 180°

Angles in a triangle add up to 180°

starting at right

180 - 101 = 79° at right side angle in triangle

now solving left side angle

180 - 38 - 79 = 63°

now solving x using left side angle, must add to 180°

x + 63 = 180°

x = 117°

Answer 2

Answer:

117

Step-by-step explanation:

101=38+(180-x)

101-38=180-x

63=180-x

x=180-63=117
