Question

the angles of a triangle are in AP if it's smallest angle is 30 degree find the remaining angles

Answer 1

it can be 60 and 90 because d=30 can be used here and sum of all angles of triangle is 180

Answer 2

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°

hope it helps.... regards
