Question

In the following figure, find​

Answer 1

Step-by-step explanation:

angle PRQ + angle PR..=180(supplementary angle)

y + 140 = 180

y = 180-140

y = 40

angle x + angle x + angle y = 180(sum of all angles of

triangle is 180)

2x + 40 = 180

2x = 180-40

2x = 140

x = 140/2

x = 70

x = 70,

y = 40
