Triangles and Trigonometry

Definition

Use properties of similar and isosceles triangles, the pythagorean theorem, or basic trigonometric ratios to solve triangles. Relate basic trigonometric expressions to right triangles.

Example

A radar on a boat records the positions of 2 islands, $A$ and $B$, and the angle between them, as shown in the diagram below. If the units on the diagram are in miles, what is the distance $d$ between islands $A$ and $B$ to the closest mile?
