Question

Find the value of x and y.

Answer 1

Answer:

» y + 130⁰ = 180⁰

» y = 50⁰ ... linear pair axiom.

» x + 70⁰ + 50⁰ = 180⁰

» x = 60⁰ ... sum of all angles of triangle.

Answer 2

Answer:

x = 60° and y = 50°

Step-by-step explanation:

y + 130 = 180°

y = 180 - 130

y = 50°

70 + 50 + x = 180 (angle sum property of triangle)

120 + x = 180

x = 180 - 120

x = 60°
