Question

2. In a triangle one angle is 60° and the measure of one of the other two angles is half
of the other. Find the measure of the smallest angle of triangle
​

Answer 1

Answer:

let the smaller angle be x

one angle is half the other means bigger angle is twice the smaller

bigger angle is 2x

now

x + 2x + 60 = 180

x + 2x = 180 - 60 = 120

3x = 120

x = 120/3

x = 40.

So, the smallest angle is 40°
