Question

In the figure, find the values of r and y.​

Answer 1

Answer:

y+140=180(because, lineqar angles)

y=180-140=40

x+70+y=180(angles in a triangle)

x+70+40=180

x=180-110=70

Answer 2

Answer:

y + 140⁰ = 180⁰ (linear pair)

y = 180 - 140⁰

y = 40⁰

x + y + 70⁰ = 180⁰ (angle sum property of triangle)

x + 40⁰ + 70⁰ = 180⁰ (putting value of y)

x + 130⁰ = 180⁰

x = 50⁰
