Question

Jeff walked 54 meters along a river bank and saw a dock directly opposite him on the other side of the river. The river is 24 meters wide at the point where he saw the dock, as shown in the diagram below

Answer 1

Step-by-step explanation:

Data

d1 = 54 m

d2 = 24 m

d3 = ?

Formula

We can use the pythagorean theorem to solve this problem

d3² = d1² + d2²

Substitution

d3² = 54² + 24²

Simplifying

d3² = 2916 + 576

d3² = 3492

d3 = 59.1 m

Result

d3 = 59.1 meters
