Question

The three angles of a triangle are in arithmetic progression. The smallest angle is 50

Answer 1

Answer:

Step-by-step explanation:

Smallest angle = 50°

Let the difference be d

Then other angle are 50°+d and 50°+2d

Sum of all angles of triangle = 180°

⇒50°+(50°+d) +(50°+2d) = 180°

⇒3d = 180° - 150° = 30°

⇒d = 10°

So, others angles are 50°+10° = 60° and 50°+ 20° = 70°
