What is the measure of the missing angle in this triangle ?

answer:

25 degrees

step-by-step explanation:

in any triangle the sum of all the interior angles add up to 180 degrees.

so 120+35 is 155

180-155=25

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°
