Which statements can be deduced from the picture? (Select ALL that apply) A: ∠1 ≅ ∠2
B: ∠5 ≅ ∠7
C: m∠7 + m∠4 =180°
D: ∠1 ≅ ∠7

∠5 ≅ ∠7

m∠7 + m∠4 =180°

Step-by-step explanation:

no explanation

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°

i suppose it should be (y=2x-5)
