Elise is measuring the angles of a triangle. She measures the first two and gets 30° and 100°. What should be the measure of the third angle?
A) 50°
B) 60°
C) 130°
D) 230°

Respuesta :

The sum of angles in a triangle is 180°.
To obtain the third angle (let's call it x), we simply calculate thus:


30° + 100° + x = 180°

130° + x = 180°

x = 180° - 130°

x = 50° ... (A)
