Question

two adjacent angles of a parallelogram are (3x-4)°and (3x+16)° find the value of x and hence find the measure of the two angles STEP BY STEP ​

Answer 1

Answer:

80° and 100°

Step-by-step explanation:

(3x-4)°+(3x+16)°=180° (adjacent angles are supplementary)

3x-4+3x+16=180

6x+12=180

6x=180-12

6x=168

x=168/6=28

So, the measure of the angles are- (3x-4)°=3*28-4= 84-4=80°

(3x+16)°=3*28+16=84+16=100°
