Plzzz answer I will give brainiest

77 inch ²

Step-by-step explanation:

Area of the triangle=1/2(b*h)

Where base=14 inch and height=11 in.

Area of triangle=1/2(14*11)

Area=7*11

Area=77 inch²

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°
