Question

In triangle ABC , if angle a + angle b =125 degree and angle a +angle c =113 degree find angle a , b and c

Answer 1

Answer:

∠A = 58° ∠B = 67° ∠C = 55°

Step-by-step explanation:

Given,

∠A + ∠B = 125°

∠A +∠C = 113°

Now,

The angle sum property of triangle,

∠A + ∠B + ∠C = 180°

125 + ∠C = 180

∠C = 180 - 125

∠C = 55°

And,

∠A + ∠B + ∠C = 180°

∠B + 113 = 180

∠B = 180 - 113

∠B = 67°

Again,

∠A + ∠B + ∠C = 180°

∠A + 67 + 55 = 180

∠A + 122 = 180

∠A = 180 - 122

∠A = 58°

Hence,

∠A = 58°  ⇒ANSWER

∠B = 67°  ⇒ANSWER

∠C = 55°  ⇒ANSWER
