Question

find angle Z.
in triangle​

Answer 1

Answer:

Solution:

Angle y and angle of measure 56° are supplementary. Hence

y + 56° = 180°

Solve for y

y = 180 - 56 = 124°

Angle x and angle of measure 144° are supplementary. Hence

x + 144 = 180°

Solve for x

x = 180 - 144 = 36°

The sum of angles x, y and z of the triangle is equal to 180°

x + y + z = 180

Substitute x and y by their values found above.

36 + 124 + z = 180

Solve for z.

z = 20°
