Question

12345678910 The measures of two consecutive angles of a parallelogram are in the ratio 6:3. What is the measure of an acute angle of the parallelogram?

Answer 1

60

Explanation:

Answer 2

60°

Consecutive angles in a parallelogram are supplementary.

The smallest angle is x and the largest angle is 180 − x.

largest angle/smallest angle = 6/3 (as a fraction) = 180 − x/x

6x = 540 − 3x

9x = 540

x = 60
