Question

3. In ∆ ABC,if 3angle A=4angle B=6 angle C, calculate angle A, angle B and angle C ​

Answer 1

Step-by-step explanation:

A=4

B=6

C=x

a+b=c

4+6=10

C=10

Answer 2

angle B= (3/4) angle A

angle C=(1/2) angle A

Step-by-step explanation:

3 angle A= 4 angle B = 6 angle C

By angle sum property of a triangle,

angle A + angle B + angle C = 180°

angle A + (3/4)angle A + (1/2)angle A=180°

(9/4)angle A=180°

angle A = 180°(4/9)

angle A=80°

Therefore, angle A=80°

angle B=(3/4) angle A =(3/4)(80°)

=60°

angle C=(1/2) angle A =(1/2)(80°)

=40°
