Question

If two angles measure 50° and 80% what is the measure of third angle?

Answer 1

Answer:

Its a triangle,

and 3rd angle is 50°

Explanation:

Sum of angles of triangle = 180°

if the two angles are represented by x and third as y,

x + x + y = 180°

50° + 80° + y = 180°

130° + y = 180°

180° - 130° = y

y = 50°
