Question

The ratio of the measures of the three angles in a triangle is 2:9:4. Find the measures of the angles.

Answer 1

Answer:

Step-by-step explanation:

let angle 1 = 2x

let angle2 = 9x

let angle 3 = 4x

angle 1 + angle2 +angle3=180    

2x+9x+4x=180

15x=180

x=180/15=12

x=12

angle 1 = 2*12=24

angle 2 = 9*12=108

angle 3 = 4*12=48

angle 1 + angle2 +angle3=180    

24+108+48=180

hence proved
