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:
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
