Question

the angle of a triangle are in the ratio 1:3:5 find the largest angle of a triangle

Answer 1

Hii frnd...

Using traingle sum property...
1x+3x+5x=180
9x=180
x=20 degree.

First angle:20 degree
Second angle: 60 degree
Third angle:100 degree

So third angle is the largest.

Hope it helped u!!!

Answer 2

let the angles be x, 3x, and 5x.
Angle sum rule of triangle
x + 3x + 5x = 180
9x = 180
x = 20



Thus ,
Largest Angle = 5x = 5*20 = 100
