Question

Find Angle of triangle.​

Answer 1

Answer:

Solution:

The sum of the angles of the triangle on the right side is equal to 180°. Hence

w + 131 + 32 = 180

w = 180 - 131 - 32 = 17°

Angle v and the angle with measure 132° are supplementary. Hence

132 + v = 180

v = 180 - 132 = 48°

The three angles of the triangle in the middle add up to 180. Hence

v + z + 122 = 180

z = 180 - 122 - v

z = 180 - 122 - 48 = 10° , v = 48 found above

Angle x and the angle with measure 122° are supplementary. Hence

x + 122 = 180

x = 180 - 122 = 58°

The three angles of the triangle on the left side add up to 180. Hence

x + 43 + y = 180

y = 180 - 43 - x

y = 180 - 43 - 58 = 79° , x = 58 found above.
