Question

in triangle abc if 20A=12B=15C find all the angle of the triangle​

Answer 1

Answer:

Answer:

Step-by-step explanation:

angle A=A, angle B=B, angle C=C

given,

A-B=15°→A=15+B

B-C=30°→C=B-30

by angle sum property of triangle

A+B+C=180°

B+(15+B)+(B-30)=180

3B-15=180

3B=180+15

B=195/3

B=65°

So,

A=65+15=80°

B=65°

C=65-30=35
