Question

two hikers start a trip from a camp walking 1.5 km due east. they then turn due north and walk 1.7 km to a waterfall. to the nearest tenth of a km, how far is the waterfall from the camp?

Answer 1

First of all, for problems like these you always want to draw a picture. In this case, you would draw a straight line going right and label it 1.5 km, and from the end of that line you would draw a straight line going up and label it 1.7 km.

Answer 2

Now, because you went (theoretically) straight up from when you walked east, you turned at a 90 degree, or, a right angle. Thus, you have the makings of a right triangle.

Answer 3

So, to find your answer, you can just apply the standard law of right triangles: \[a ^{2}+b ^{2}=c ^{?}\]

Answer 4

then find the hypotenuse

Answer 5

Or, 1.5^2 + 1.7^2 = 5.14^2

Answer 6

Which is the hypotenuse.
