The measures of two angles of a triangle are 25° and 87°. Is the triangle acute, right, or obtuse?
A. Acute; the measure of the third angle is 68°. So all three angles are acute.
B. Acute; the measure of the third angle is 78°. So all three angles are acute.
C. Obtuse; 25° + 87° = 112° and 112° is an obtuse angle.
D. Right; 25° + 87° = 112° and 202° – 112° = 90°.
