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. Which measurement is closest to the distance, in meters, of jeffs starting point.
a.30.0
b.59.1
c.78.0
d.48.4

Answer 1

Answer:

The answer to your question is letter b

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

Answer 2

The measurement is closest to the distance, in meters, of jeffs starting point d3 is 59.1 meters

We have given data

d1 = 54 m

d2 = 24 m

d3 = ?

What is the formula for the Pythagorean theorem?

The Pythagorean theorem

$hypotenous^2=side^2+side^2$

d3² = d1² + d2²

Substitution

d3² = 54² + 24²

Simplifying above we get,

d3² = 2916 + 576

d3² = 3492

d3 = 59.1 m

Therefore, measurement is closest to the distance, in meters, of jeffs starting point d3 is 59.1 meters

Option b is correct.
