Question

The distance from point A to one end of the pond is 190 yards, and the distance from A to the other end of the pond is 208 yards. What is the length of the pond, x, to the nearest yard?

Answer 1

Answer:

x = 150 yards

Step-by-step explanation:

Looking at the diagram, a triangle, ABC is formed.

Let the length of AB be c, so c = 208 yards

Let the length of AC be b, so b = 190 yards

Length of BC = x

To determine x, we will apply the cosine rule since we know two sides and one angle. The cosine rule is expressed as follows

a^2 = b^2 + c^2 - 2bcCosA

Therefore

x^2 = 208^2 + 190^2 - 2×208×190 Cos44

x^2 = 43264+ 36100 - 79040 × 0.7193

x^2 = 79364 - 56853.472

x^2 = 22510.528

x = √22510.528

x = 150 yards

Answer 2
