Question

a b c are three angles of a triangle if Angle B minus angle A = 45 degree angle B minus angle c equal to 15 degree then find the values of Angle A Angle B and c​

Answer 1

Answer:

A=35°,B=8O°,C=65°

Explanation:

If B-A=45

and B-C=15

Then, A= -(45-B)= -45+B

C= -(15-B)= -15+B

According to angle sum property:

A+B+C=180

=B-45+B-15+B=180

= 3B-60=180

=3B=180+60

=3B=240

=B=80

Now, A= -45+80=35

C=-15+80=65
