Question

The measures of angles A and B of parallelogram ABCD are in the ratio of 2: 7. Find the measure of angle C.​

Answer 1

Answer:

40°

Step-by-step explanation:

let angle A=2x and angle B=7x 2x+7x=180° ...(°•° adjacent angles of parallelogram are equal) 9x=180° x=180°÷9 x=20° angle A=2x=2×20°=40° angle A=angle C =40°

Answer 2

Answer:

Angle c=40
