Question

3)

Three angles are in the ratio 2:3:5
The smallest angle is 50
Work out the sizes of the other two angles

Answer 1

The other two angles are 75° and 125°.

Explanation:

Let three angles are 2x, 3x and 5x.

The smallest angle is 50.

It means,

2x = 50

x = 25

So,

3x = 3(25) = 75°

5x = 5(25) = 125°

So, the other two angles are 75° and 125°.
