A forest ranger spots a lost hiker in distress in a dense forest. The ranger is located 50 meters from a marked trail and the hiker is 80 meters into the forest and 120 meters north of the ranger's position. Determined to rescue the hiker, the ranger runs and then navigates through the dense vegetation to reach the hiker directly.
Assuming the ranger and hiker are initially at the same elevation, and the ranger's path is a straight line, how far north from their original position on the trail will the ranger enter the forest? (Hint: work out the value of y in the diagram.)
In an alien world, there are two skyscrapers named Rivers and Everlast. The building Rivers stands 1,500 meters tall, and its shadow in a picture is 2.4 centimeters. Meanwhile, the closest skyscraper, Everlast, casts a shadow of 1.5 centimeters on the same picture. Assuming that the angles of sunlight are similar for both skyscraper peaks and that the picture was taken under consistent lighting conditions, what is the height of Everlast?
Determine the values of the six trigonometric functions for the angle illustrated. When necessary, rationalize the denominator.

To find the distance across the pond, AB, an engineer uses field tape to measure AC and obtained a length of 31.2 m. This length results in angle measures of C = 41° 12' and B = 48° 48'. Find length AB. Round your answer to one decimal place.

Ricky is standing at a corner of a square-shaped roof. He is flying a kite at a height of 230 m above the center of the roof. The side of the square-shaped roof is 500 m. Find the angle of elevation, α, of the kite if the base of the triangle (as shown in the figure) is half the length of the diagonal of the square-shaped roof. Round your answer to two significant figures.

An engineer is designing a radar system for an aircraft to detect and track targets in multiple dimensions. To achieve accurate tracking, the engineer needs to use a special radar antenna that can adjust its beam direction with prisms. The amount of beam shift caused by the prism is measured in prism units. The radar system needs to correct 24 prism units horizontally and 7 prism units vertically. A prism that compensates for both requirements should have length 'L' and be set at angle 'α.' Determine the values of 'L' and 'α' in the figure.
