Question

of its sides.
5. Two adjacent angles of a parallelogram are (4x - 15)° and (5x – 3)º.
Find the measure of all angles of the parallelogram.​

Answer 1

Answer:

Measure of all angles in the parallelogram are 73, 107, 73, 107

Step-by-step explanation:

(4x-15)+(5x-3)=180 (adjacent angles in a parallelogram are supplementary)

4x-15+5x-3=180

9x-18=180

9x=180+18

9x=198

x=198/9

x=22

4x-15= 4(22)-15= 88-15= 73

5x-3= 5(22)-3= 110-3= 107
