Question

The angles of a triangle are in the ratio
1:3:5. Find the measure of each one of the
angles.​

Answer 1

Answer:

20°, 60° and 100°

Step-by-step explanation:

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

Sum of all angles in a triangle us 180°.

So,

x + 3x + 5x = 180

=> 9x = 180

=> x = 180/9

=> x = 20

Hence, the angles of the triangle are

x = 20°

3x = (3×20)° = 60°

5x = (5×20)° = 100°
