Andrew wants to build a slide for his daughter’s tree house. if the tree house is 5 ft off the ground and he wants the slide to make a 30° angle with the ground, how long a sliding board does he need to buy? (round to the nearest foot.)

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

$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
