Question

The Angles of a triangle are in the ratio of 1:3:5 find their measures

Answer 1

Let the ratio be 1x,3x and 5x

By angle sum property of triangle we have,

1x+3x+5x=180

9x=180

x=180/9

x=20

Now,

1x=1×20=20

3x=3×20=60

5x=5×20=100

Hence all the angles of triangles are 20,60 and 100.

Hope it helped
