Question

the angles of a triangle are at a ratio of 4:5:3.find the angles

Answer 1

Let the angles be 4x, 5x, 3x
4x + 5x + 3x = 180 ( Angle Sum Property of Triangle)
12x = 180
x = 180/12
x = 15

4x = 4*15 = 60
5x = 5*15 = 75
3x = 3*15 = 45

Answer 2

Answer:

60, 75, 45

Step-by-step explanation:

Let the ratio be 4x:5x:3x

4x+5x+3x=180                [Angle Sum Property of a Triangle]

12x=180

x=180/12=15

Therefore, 4x=4 x 15 = 60

5x=5 x 15 = 75

3x=3 x 15 = 45
