Question

the angle of triangle are in the ratio 5:3:7. what is the type of triangle ​

Answer 1

Answer:

scale triangle is correct

Answer 2

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

Sum of angles in a triangle = 180°

5x + 3x + 7x = 180°

15x = 180

x = 180/15

x = 12°

ANGLE 1: 5x = 5*12 = 60°

ANGLE 2: 3x = 3*12 = 36°

ANGLE 3: 7x = 7*12 = 84°

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