Question

The angles of the triangle are in the ratio 5:3:7. Find the largest angle of the triangle

Answer 1

hey mate here is ur ans

let the ratio constant be x
so the angles are 5x, 3x and 7x

we know that the angle sum of triangle is 180°
so=>5x+3x+7x=180
=>15x=180
=>x=180/15=12

so the angles are
angle 1=5*12=60°
angle 2=3*12=36°
angle 3=7*12=84°

so the third angle is the greatest (84°)


hope it helps you frnd

Answer 2

84° will be the largest angle
