A: What is the perimeter of HOUSE? perimeter of HOUSE =

(round to the nearest hundredth - two decimal places)

B: What is the length of OH?

(round to the nearest thousandth - three decimal places)

C: What is the midpoint of OU?

D: Which is longer, OH or EH?

E: What is the perimeter of the triangle HOU?

perimeter of triangle HOU

(round to the nearest hundredth - two decimal points)

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°

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
