Question

In ΔABC, if 3∠A=4∠B=6∠C. Find the value of ∠A, ∠B, ∠C in degree.​

Answer 1

Answer:

A=80 ; B = 60 and C = 40.

Step-by-step explanation:

3A=6C and 3A=4B

THUS, A/2=C .............{1}

   and 3/4A=B..............{2}

we know, A+B+C=180......................(angles of a triangle)

from {1} and {2},

A+3/4A+A/2=180

THUS, 9/4A=180

9A=720

A=80

Put A=80 in {1} and {2}

thus, C=40

and B=60.
