Question

The three angkes of triangle are in the ratio 1:2:1 . Find all the angles o

Answer 1

Answer:

Let the common multiple be x.

So angles of triangle are x, 2x, x.

According to angle sum property of a triangle,

x+2x+x=180°

4x=180

x=180/4

x=45

x=45, 2x=2*45=90, x=45

Therefore angles of a triangle are 45°, 90°, 45°.
