Question

The angles of a triangle are in A.P . If smallest triangle is 30°, the triangle is ​

Answer 1

smallest angle = 30°

let the difference be d

then other angle are 30°+d and 30°+2d

∵sum of all angles of triangle = 180°

⇒30°+(30°+d) +(30°+2d) = 180°

⇒3d = 180° - 90° = 90

⇒d = 30°

so others angles are 30°+10° = 40° and 30°+ 20° = 50°

hope it helps.... regards
