Question

In ∆ ABC if angle B is three times of angle A;
and angle C is 5 times of angle A, then difference
between angle C and angle A will be......
please give me correct answer​

Answer 1

Answer:

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

HOPE THIS CANE OUT TO BE BEST

Answer 2

Answer:

40

Explanation :-

angle b = 3a

angle c = 5a

Now , acc to A.S.P of ∆

angle a + angle b + angle c = 180°

a + 3a + 5a = 180°

9a = 180°

a = 180/9

a = 20°

so,

angle a = a = 20°

angle b = 3a = 3× 20 = 60°

angle c = 5a = 5× 20 = 100°

Now , angle c – angle a

= 100-20

= 80°
