Question

If the angles of a triangle are in the ratio 5:3:7 then find the triangle type​

Answer 1

$\large\bf{\underline\orange{Answer \:↝}}$

Angles of triangle are in the ratio 5:3:7

Therefore,

5x + 3x + 7x = 180°

15x = 180°

x = 12°

5x = 5 × 12 = 60°

3x = 3 × 12 = 36°

7x = 7 × 12 = 42°

Since ,all angles are less than 90°

Therefore, the triangle is an acute angled triangle.

Answer 2

Answer:

5x + 3x + 7x = 180 (Angle sum property)

15x =180

x= 180/15

x = 12

It is an acute angle traingle
