1. 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

   ∘

2. Answer:

   supplementary angle =180..

   2x+5x=180

   7x=180..

   x=180/7=25.71..

   2*25.71=51,.42

   5*25.71=128.58
