the pythagorean theorem
right triangles trigonometry

using the side lengths, determine whether the triangle is acute, obtuse, or right.

a.) acute

b.) obtuse

c.) right

This is C right angle triangle

Step-by-step explanation:

$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
