Given: pstr is a parallelogram m∠t: m∠r=1: 3, rd ⊥ ps , rm ⊥ st find: m∠drm

As we know the sum of consecutive angles of a parallelogram is 180 degrees, we can calculate them. 1k+3k=180 and k=45. It is the measure of the angle R (in the picture, angle B). Since MR is perpendicular, we can find angle MRT (in the picture it is BCF). And it is 45 degree according to the theorem about the sum of all angles of a triangle. From here, we can say that ∠DRM=135-45=90 degree.

Answer:

$4034.40

step-by-step explanation:

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
