Question

7. In a A ABC, if 3 ZA = 4ZB = 6 ZC, calculate the angles.

​

Answer 1

Answer:

∠A=720/9=80°

∠B =3/4*80=60°

∠C=80/2=40°

Step-by-step explanation:

3 ∠C = 4∠B = 6 ∠C

∠B=3/4 ∠A

∠C=3/6 ∠A=∠A/2

SO ∠A + ∠ B + ∠C=180

∠A+3/4∠A+∠A/2=180

1/4(4∠A+3∠A+2∠A)=180

9∠A=180*4

∠A=720/9=80°

∠B =3/4*80=60

∠C=80/2=40°
