Question

the angle of a triangle are in the ratio 3 : 5 : 7. Find the measure of each angle of the triangle.


HINT = WE KNOW THAT THE SUM OF THE ANGLES OF A TRIANGLES IS 180°.​

Answer 1

Answer:

sum of angles in a triangle = 180°

given , ratio = 3:5:7

so , 3x + 5x + 7x = 180°

15x = 180°

x = 12.

The angles are :

• 3 × x = 3 × 12 = 36°
• 5 × x = 5 × 12 = 60°
• 7 × x = 7 × 12 = 84°
