Question

the angle of triangle are in the ratio 3:5:7.find the measure of these angle ​

Answer 1

let the angles be 3x 5x and 7x

by angle sum property

3x + 5x+ 7x = 180

15x = 180

x = 180/15

x = 12

1st angle = 3x = 45

2nd angle = 5x = 60

3rd angle = 7x = 84

Answer 2

$\huge\mathfrak\red{Answer!!!!}$

suppose all proportion is =x

then angles will 3x ,5x and 7x

and we know ___
any triangle three angle sum = 180
let.
3x+5x+7x=180

15x=180
x=180/15
x=12.

then angles are===
3×12=36

5×12=60

7×12=84.
