We develop two different right triangles in which the opposite side to the given angle of depression is 1500 ft and the length of the runway is the y. (45°) --> tan (45°) = 1500 ft / y₁ y₁ = 1500 ft (42⁰) --> tan (42⁰) = 1500 ft / y₂ y₂ = 1665.92 ft Finding the difference between two y's, the answer would be 165.92 ft.
First subtract manny value 36.5 from Evan values 18 which will give u 18.5 cm which then u have to convert. Since 1 cm is about .4, we can multiply 18.5 by .4 to get the answer 7.4 inches
