Question
Geometry:
If the angles at a triangle are in the ratio 2:3:5, then the measures of the least angle of the triangle is ____
As per the given ratio, let us take the angle value as A, i.e. 2A, 3A, 5A.
Sum of the angles should be 180.
2A + 3A + 5A = 180 => 10A = 180 => A = 18.
Least angle = 2A = 2 x 18 = 36˚
