2. A 30-60-90 Right Triangle Word Problem
Step 1:
Make sure the triangle is a right triangle.
Step 2:
Use the special relationships of the sides to identify the missing length.
Step 3:
Write the units.
Step 1:
We're given 30°, and
can assume that when
the problem says “west”
that it's directly west.
Therefore we can assume
that angle is 90°. That
means the last angle is 60°.
Step 2:
Using the relationships
of the sides of a
triangle, you
can easily find the
missing length.
Short leg = 46 miles
If the short leg is length x, then the hypotenuse is 2x, and the longer side is x
Hypotenuse/Distance = 2 (46)
Hypotenuse/Distance = 92
miles 3
