Answer 1

Answer:

Please look at the attachment. Hope you understand it.

Answer 2

The sum of all angles in parallelogram = 360°

the sum of ratio ➡7+2=9

360/9=40

By the ratio

the angles are 1.(40×7) and 2.(40×2)

=280° and 80°

then other angles are

280/2=140 and 80/2=40

the four angles are 1. 140°

2. 140°➡ adjacent angles

3. 40°

4. 40°➡adjacent angles
