Question

the angle of a triangle are in the ratio 2:5:2 .find the degree measures of each angle of the triangle ​

Answer 1

Answer:

We know that the sum of all angles of a triangle is 180'

Ratio=2:5:2

Let the value of angles be 2x,,5x,2x

So, 2x +5x+2x =180

9x=180

x=20

Hence value of each angle is

2x=2×20=40'

5x=5×20=100'

2x=2×20=40'
