2. The angles of a triangle are in the
ratio 3:5:7. The triangle is
​

Answer 1

Let angles of a triangle be angle A, angle B, and angle C. Since, all angles are less then 90°, hence the triangle is an acute angled triangle.

Answer 2

Step-by-step explanation:

ratio = 3:5:7

therefore,

3x + 5x + 7x = 180°

15x= 180°

x= 180°÷ 15

x=12°

3x = 3×12°

= 36°

5x = 5×12°

= 60°

7x=7×12°

= 84°

36°+60°+84° = 180°
