Question

The adjacent angles in a parallelogram are (3x+10)0and (x+20)0. Find the measure of the angles.

Answer 1

Answer:

122.5°, 47.5°, 122.5°, 47.5°.

Step-by-step explanation:

Sum of Adjacent angles in parallelogram = 180°.

3x +10 + x+20 = 180°

4x + 30 = 180°

4x = 150°

x = 37.5°

So,

First two angles = (3 x 37.5) + 10 = 122.5°

Another two angles = (37.5 + 10) = 47.5°

So, the angles are 122.5°, 47.5°, 122.5°, 47.5°.
