Question

the angles of a triangle are in the ratio 3: 5 : 7 .find the measures of these angles.​

Answer 1

Answer:

36 deg, 60 deg, 84 deg

Step-by-step explanation:

Let the common factor be x

Then, the angles are 3x deg, 5x deg, 7x deg

Implies that, 3x + 5x + 7x =180 deg (Angle sum property)

Thus, 15 x = 180

Thus, x = 180/15

Thus, x = 12 deg

Thus the angles are 12×3 = 36 deg, 12×5 = 60 deg, 12×7 = 84 deg
