Question

If one angle of a triangle is 100° and the other angles are in
the ratio of 2:3. Find the angles​

Answer 1

Let first angle be 2x

Let second angle = 3x

So by angle sum property of a triangle

2x + 3x + 100 = 180

5x + 100 = 180

5x = 80

x = 16

So

first angle = 2x = 32

Second angle = 3x = 48
