A giant right triangular sculpture has two legs with lengths 20 meters and 40 meters. What is the measure of the smallest angle in this sculpture? Round your answer to the nearest degree. 15°
27°
30°
43°

30 degrees

Step-by-step explanation:

we need to compute angle A and angle B (see figure below)

hence,

this implies that A=60 degrees.

Since interior angles of a triangle add up 180 then,

A+B+90=180

60+B+90=180

B+150=180

B=180-150

B=30 degrees

which is the smallest angle

to rewrite a literal equation you may need to divide by a number, or by a variable.

$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
