Solve the right triangle shown in the figure. (Round your answers to two decimal places.)

Step-by-step explanation:

(3). cos A =

cos A = = 0.1 ⇒ A ≈ 84.26°

B ≈ 5.74°

C = 90°

a ≈ 17.61

(4). cos 16° = ⇒ x ≈ 82.18 ≈ 82.2 ≈ 82

$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
