The shape formed by the three is a right triangle because the angle formed at Rachael's position is 90°.
The known values are 90°, 55° and 45 ft.
Since the sum of all angles in a triangle is 180 degrees, we can easily solve for the angle formed by Jamie: 180°-90°-55° = 35°.
For the distance between Jamie and Lance (JL): cos 55° = 45/JL
JL = 78.455 feet.
For the distance between Jamie and Rachael (JR): tan 35° = 45/JR
JR = 64.267 feet.
