Question

if one of the angle of a triangle is 35' and the second is twice of first.Find the third angle

Answer 1

Hey...!!!

One angle of a triangle = 35°
Second angle = (2 x 35)°
= 70°
Third angle = x (let)

So,
35 + 70 + x = 180
105 + x = 180
X = 180 - 105
X = 75

So,
Third angle = 75°

Hope it helps...!!!
