Question

One angle of a triangle measures 104°. The other two angles are congruent.

Enter and solve an equation to find the measure x of the congruent angles.

Answer 1

X = 38°

Explanation:

The sum of all angles of a triangle = 180°

104° + X + X = 180°

104° + 2X = 180°

2X = 180° - 104°

2X = 76°

X = 76° / 2

X = 38°
