Question

the angles of a triangle are in a A.P.the smallest angle is 30 degree.find all the angles of a triangle.​

Answer 1

Answer:

Step-by-step explanation:

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°
