The angles of the triangle are in the ratio: 5:3:7

Let the angles be 5x,3x,7x

By Angle sum property,

5x+3x+7x=180

15x=180

x=12

Thus, angles are, 60∘,36∘ ,84∘

scince, all the angles are less than 90∘ , it is an acute angled triangle.

Answer 2

Answer:

an acute angled triangle.

Step-by-step explanation:

let the angles be 5x, 4x and 3x

5x+4x+3x=180°《ASP》

12x=180

x=180/12

x=15

therefore, 5x=5×12=60°

4x=4×12=48°

3x=3×12=36°

since all the angles are less than 90°, thus the triangle is an acute angled triangle.

thanks buddy for so much thanks!!!
