- There is a boy named Jake and he decides to get a look of the Hollywood sign in LA. Jake wants to know how high the sing is from him. He knows the angle of elevation is 80 degrees. The length of the base where he is standing to the sign is 15 ft. Jake must use sin(80)15 to find the height. The height is 14.772 ft
- Jake is now in San Francisco and knows that the angle of elevation from him to the top of the Golden Gate Bridge is 2 degrees. Jake is also 300 feet from the bridge. Jake uses 120cos(89). Jake is 299.817 ft away from the top of the Golden Gate Bridge.

- Jake is on top of a building. Jake wants to know how high is the bird on the building next to him. Jake is about 40 feet lower than the bird. Jake is also about 45 feet away from the building. sin^-1=40/45 is about 62.7 degrees. tan(62.7)=40/x = 40tan(62.7). Jake is 77.498 feet away from the bird.
- Jake is now in London at the Big Ben. Jake sees a bird on Big Ben at about 114 feet high and with an angle of elevation of 85 degrees. tan(85)=114/x = 114tan(85). The bird is 1303.026 feet away from the bird
