Which expression is equivalent to (20+4)

O 498 +16
O 496 + 1699 +16
O 408 +8
O 4gº + 16g8+8

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°

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
