1 answer:
Sliva [168]2 years ago
7 0

Answer: See the screenshot below.

Explanation:

We'll be using these trig functions

  • sine = opposite/hypotenuse
  • cosine = adjacent/hypotenuse
  • tangent = opposite/adjacent

The inverse of those help us find the angle. Notation like arcsine is the same as inverse sine denoted as \sin^{-1} on many calculators.

The decimal results are approximate.

Answer:

9 yards

Step-by-step explanation:

A square has 4 equal sides, this means the 2 sides we will multiply to get the area are going to be the same. Since it says 81 yards squared and the shape is a square, we can do the square root of 81 which is 9.
