Question

if the two adjacent angle of a parallelogram are in the ratio 3:7 the largest angle is​

Answer 1

Answer:

7x = 126°

Step-by-step explanation:

Let the angles be 3x and 7x

3x + 7x = 180° (adjacent angles of parallelogram are supplementary)

10x = 180°

x = 180/10

x = 18°

3x = 3(18) = 54°

7x = 7(18) = 126°

Therefore, 7x is the largest angle with a measurement of 126°
