First draw a right triangle using the lighthouse as reference. Draw a dot (lighthouse) draw a line downward (south) with 2.2 km measurement. Next, draw a line to the right of the lighthouse (16.8 km)
The two legs are 2.2 km and 16.8 km. To complete the statement, we need to solve for the hypotenuse of the right triangle.
Using the Pythagorean Theorem:
Assign a = 2.2 km
b = 16.8 km
so,
c^2 = a^2 + b^2
2.2^2 + 16.8^2 = c^2
Therefore, the value of c is 16.94 km.
