Question

The angle of a triangle are in the ratio 1:3:5.find the measure of each one of the angle

Answer 1

Dear student,
Let x be the common multiple.
Then , the angles of the triangle will be x,3x,and 5x.
Now, x+3x+5x=180 (Angle sum property)
=> 9x=180
=>x=20
Then, the angles will be,
x=20
3x=3$\times$20=60
5x=5$\times$20=100
