Question

The angles of a triangle are in the ratio 1:3:5. How much is the larger

angle?​

Answer 1

Step-by-step explanation:

Let angle angles be 1x, 3x and 5x

Sum of angles of a triangle= 180°

$1x \: + 3x + 5x \: = 180 \\ 9x = 180 \\ x = \frac{180}{9} = 20$

∴ 1x= 20

3x= 60

5x =100

Answer 2

Step-by-step explanation:

let the the angles be x ....

x,3x , 5x = x+3x+5x=180 ( angle sum property of a triangle)

9x=180

=180/9x=20

x=20

=3.x =3*20=60

=5x =. 5*20=100

angle 100 degree is larger angle
