Question

Type the correct answer in each box.

The value of x is °, and the value of y is
°.

Answer 1

x = 60°, y = 50°

Explanation:

We know: the angles measures in a triangle add up to 180°.

z + 50 + 60 = 180

z + 110 = 180 subtract 110 from both sides

z = 70°

x + 50 + 70 = 180

x + 120 = 180 subtract 120 from both sides

x = 60°

Angles x, y and z are on one side of a straight line. Therefore they add to 180°.

x + y + z = 180

60 + y + 70 = 180

y + 130 = 180 subtract 130 from both sides

y = 50°

Answer 2

x = 60°, y = 50°

Explanation:

We know: the angles measures in a triangle add up to 180°.

(look at the picture)

z + 50 + 60 = 180

z + 110 = 180 subtract 110 from both sides

z = 70°

x + 50 + 70 = 180

x + 120 = 180 subtract 120 from both sides

x = 60°

Angles x, y and z are on one side of a straight line. Therefore they add to 180°.

x + y + z = 180

60 + y + 70 = 180

y + 130 = 180 subtract 130 from both sides

y = 50°
