Question

If two angles of triangle are in AP. If the smallest angle is 30 degree. Find the remaining angles...​

Answer 1

Answer:

angle 1 = 30

angle 2 = 30 + a

angle 3 = 30 + 2a

180 = 30 + 30 + a + 30 + 2a (angle sum property)

180 = 90 + 3a

3a = 180 - 90 = 90

a = 90/3 = 30

angle 1 = 30

angle 2 = 30 + a = 30 + 30 = 60

angle 3 = 30 + 2a = 30 + 2*30 = 30 + 60 + 90

180 = 30 + 60 + 90
