1. Answer:

   let the angles be 2x and 7x

   the sum of angles will be180

   2x+7x=180

   9x=180

   x=180÷9

   x=20°

   the angles will be

   2x=2×20=40°

   7x=7×20=140°

2. Let the angles be 2x and 7x

   Angles are given supplementary

   2x+7x=180 ∘

   9x=180 ∘

   x=20 ∘

   So the angles are 2×20 ∘ =40 ∘

   and 7×20∘=140∘
