Question

What’s the value of x and y

Answer 1

Answer:

x = 60°

y = 50°

Step-by-step explanation:

Sum of all 3 angles in a triangle = 180

so

x + 50 + 70 = 180

x + 120 = 180

x = 180 - 120

x = 60

The triangle on the left, also sum of all 3 angles in a triangle = 180

unknown angle = 180 - (50 + 60) = 180 - 110 = 70

y = 180 - (60 + 70) = 180 - 130 = 50
