Question

The sum of two angles of a triangle is 80° and their difference is 20°. Find the measures of
all the angles of the triangle.

Answer 1

Answer:

The angles are 50 and 30

I hope this will help u

Answer 2

Answer:

Easy!

let angles be A, B and C.

Let A+B=80°..................... (1)

     A-B=20°  ......................(2)

Subtract and add (1) and (2).

You will get ∠B=30°, ∠A=50°

We know that sum of all angles of triangle is 180°.

∠A+∠B+∠C=180°

50+30+C=180               (∠B=30°, ∠A=50°)

∠C=100°.

Therefore, ∠A=50°, ∠B=30°, ∠C=100°
