Question

In ∆ABC angle a is four times to angle b and angle c is five times to angle b. Find the three angles

Answer 1

Answer:

it would be solved by angle sum property of triangle

Step-by-step explanation:

angle B=3A

angle C=5A

now according to property the sum of all interior angles= 180 degree

therefore,A+B+C= 180

NOW BY SUBSTITUTING VALUES

=>A+3A+5A=180

=>9A=180

=>A=20

THEREFORE

B=3A=60

C=5A=100
