În triunghiul ABC ascutitunghic, BM este inaltime ,M∈(AC) , CN inaltime ,N∈(AB) si BM=CN. Aratati ca triunghiul ABC este isoscel.

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°

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

yeah i know the problem you need. i am taking it right now. the answer is step 3
