Question

The measure of two adjcent angles of parallelogram are in the ratio 7:3 . What is the measure of each angle? 

1. 126° , 54 °

2. 90° , 180°

3. 45° , 45 °

​

Answer 1

Answer:

The answer is 1. 126°, 54°

Step-by-step explanation:

let the measure of two adjacent angles of parallelogram be 7x , 3x.

Since the adjacent angles of a parallelogram are supplementary.

7x + 3x = 180°

10x = 180°

x = 180°/ 10

x= 18°

Therefore, 7x×18 = 126°

3x×18 = 54°.
