Question

1. What do we call a triangle if the angles are in the ratio 5:3:7?​

Answer 1

Answer:

If the angles are in the ratio 5:3:7, then the triangle is. Let angles of a triangle be ∠A,∠Band∠C. Since, all angles are less then 90∘, hence the triangle is an acute angled triangle .

Step-by-step explanation:

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 ∘

Since, all the angles are less than 90 ∘

, it is an acute angled triangle.
