Question

in the parallelogram ABCC , angle a =(5x-20)°and angle b=(3x+40)°.find the measure ofall angles​

Answer 1

Answer:

1st adjacent angle=95°

2nd adjacent angle=85°

as it same for another angles

so all four angles are 95°, 85°, 95°, 85°

Step-by-step explanation:

sum of adjacent angles of a parallelogram is 180°

(3x+2) °+(5x-40) °=180°

8x-20=180

8x=180+20

8x=200

x=25

3x+20=3(25) +20=95°

5x-40=5(25) -40=85°
