Question

A parallelogram has one angle that measures 170°. What are the measures of the other three angles in the parallelogram?

Answer 1

Given-Angle A=170°
Angle C=170°(alternate angles)
Angle D=angle c+angle d(sum of int angles on same side of transversal)
170°+angle d=180°
angle d=10°
Angle d=angle b=10°(alterbate angles)
Angle A-170°
Angle B-10°
Angle C-170°
Angle D=10°
