Example Question #1 : Right Triangles And Similar Triangles
Find the area of the triangle.
Dropping the altitude creates two special right triangles as shown in the diagram. Use the area formula of a triangle to get
Example Question #2 : Right Triangles And Similar Triangles
Fire tower A is miles due west of fire tower B. Fire tower A sees a fire in the direction degrees west of north. Fire tower B sees the same fire in the direction degrees east of north. Which tower is closer to the fire and by how much?
Fire tower A; 0.24 miles
The two fire towers are equidistant to the fire.
Fire tower B; 1.29 miles
Fire tower B; 0.24 miles
Fire tower A; 1.53 miles
Fire tower B; 0.24 miles
First, realize that the angles given are from due north, which means you need to find the complements to find the interior angles of the triangle. This triangle happens to be a right triangle, so the fast way to compute the distances is using trigonometry.
Fire tower B is miles closer to the fire.
Example Question #3 : Right Triangles And Similar Triangles
Find the length of side .
In an angle-side-angle problem, Law of Sines will solve the triangle.
First find angle A:
Then use Law of Sines.
