When driving down a mountain road, you notice waming signs indicating that it is a 11% grade. This means that the slope of the road is -11/100. Approximate the amount of horizontal change in your position if you note from elevation markers that you have descended 2000 feet vertically. (Round your answer to one decimal place.)

i believe the correct answer is b.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

$4034.40

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

the answer is b.
