Question

The sum of the angles of a triangle is 180.The angles are in the ratio 1:3:5.Find the measures of each angles​

Answer 1

Step-by-step explanation:

Hi,

Let the three angles be x° , 3x° and 5x° .

Sum of all angles = 180°

x° + 3x° + 5x° = 180

9x° = 180

x = 180/9

X = 20.

Therefore,

First angle = x = 20°

Second angle = 3x = 3*20 = 60°

And,

Third angle = 5x = 5*20 = 100°

Hope it will help you :)

Answer 2

Answer:

20, 60, 100

Step-by-step explanation:

given: angles are in a ratio of 1:3:5.

Let angles be x, 3x, 5x respectively

now,

x+3x+5x=180 ( Angle sum property of a triangle)

9x=180

x=180/9

x=20

thus the angle are 20, 60, 100 respectively
