Hey mate!!!✨✨

Here's your answer...❤❤

Let the two angles be x and y.

x + y = 80°

x - y = 20°

2x = 100°

x = 100/2

x = 50°

x + y = 80°

50° + y = 80°

y = 80° - 50°

y = 30°

Let the other angle be z.

x + y + z = 180°(angle sum property of ∆)

50° + 30° + z = 180°

80° + z = 180°

z = 180° - 80°

z = 100°

Ans: The angles of the triangle are 50° , 30° and 100°.
