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

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

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft
