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 angle C​

Answer 1

Answer:

Step-by-step explanation:

Given that,

∠B - ∠A = 45°

∠B - ∠C = 15°

To find : ∠A, ∠B, ∠C

Now,

∠A = ∠B - 45° ______(1)

∠C = ∠B - 15°_______(2)

We know that all the angles in a triangle is 180°

So, A+B+C=180

Substituting 1 and 2 here, we get

∠B - 45°+∠B +∠B - 15°=180

3B = 180+45+15

3B= 240

∠B=80

Substituting ∠B in 1 and 2 , we get Angle A and C

so, A= 35 and B=65
