The angles of a triangle are described as follows: Angle A is the largest angle; it’s measure is twice the measure of Angle B. The measure of Angle C is 10 more than one-third of Angle B. Find the measures of the three angles in degrees.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
