Question

In a triangle ABC, 15A = 10B = 6C, determine A,B and C.​

Answer 1

Answer:

Thus A=54 ,B=36 and C=90

Step-by-step explanation:

15A = 10B = 6C,

15A=10B

A=10B/15

Also 10B=6C

C=10B/6

A+B+C=180

10B/15+B+10B/6=180

NOW LCM( 15,6)=30

So 20B+30B+50B=5400

100B=5400

B=54

So A=540/15=36

C=180-(A+B)

=180-(36+54)=180-90=90

Thus A=54 ,B=36 and C=90
