Question

Two adjacent interior angle of a parallelogrom
2x -15° and 7x-75° . Find all the angles of the
parallelogram​

Answer 1

2x-15 + 7x-75 =180 ( adjacent angles are supplementary in a parallelogram)

9x-90=180

x= 30

so angle 1 is 45

angle 2 is 135

angle 3= angle 1 ( opposite angles in parallelogram are equal)

angle 3 is 45

angle 2= angle 4 (opposite angles in parallelogram are equal)

angle 4 is 135

Answer 2

Answer:

2x-15°=180°

2x=180°+15°

2x=195°

x=195°/2

x=97.5°

7x-75°=180

7x=180°+75°

7x=255°

x=255°/2

x=127.5°
