Question

In angle ABC, angle A : angle B : angle C = 4:5:6, calculate angle A , angle B and angle C​

Answer 1

Answer:

∡A=48'  ∡B=60'  ∡C=72'

Step-by-step explanation:

IN THE GIVEN ΔABC,

ANGLES A, B AND C ARE IN THE RATIO 4:5:6

LET THE ANGLES BE 4x,5x,6x.

Using angle sum property of triangle,

4x+5x+6x=180

15x=180

x=180/15

x=12

Hence,

∡A = 4x= 4*12= 48'

∡B = 5x= 5*12= 60'

∡C = 6x= 6*12= 72'
