Question

in a triangle abc angle A is 25 degree more than Angle B and angle C is 10 degree less than Angle B what are the angles of the triangle

Answer 1

hope u understand the calculations yourself

Answer 2

∠A = 80°, ∠B = 55° and ∠C = 45°

Step-by-step explanation:

Let ∠A = x + 25°, ∠B = x and ∠C = x - 10°

To find,  the angles of the triangle = ?

We know that,

Sum of anges of triangle = 180°

∴ ∠A + ∠B + ∠C = 180°

⇒ x + 25° + x + x - 10° = 180°

⇒  3x + 15° = 180°

⇒  3x = 180° - 15° = 165°

⇒ x = 55°

∴ x + 25° = 55° + 25° = 80° and

x - 10° = = 55° - 10° = 45°

Hence, ∠A = 80°, ∠B = 55° and ∠C = 45°
