Question

Answer for 14 and 15 please please

Answer 1

Ans 14) Let angles be ∠A,∠B and ∠C

So, ∠A+∠B∠C = 180
      2∠C = 180° -110°
        so, ∠C = ∠B =  35°

Ans 15) By Angle sum Property,
                   x+10+x+40+2x-30 = 180
                 4x+20 = 180
          so, x = 40

So, Angles are 50,90 and 40

So, It is a Right angled Triangle
