first, consider that 25 = 5^2, and -25 = -1*25 = -1*5^2.
Then, you can write:
because i = √-1.
Hence, the answer is 5i
Two buildings are 200 feet apart. The height of the taller building is 50 ft. The angle of depression from the top of the taller
building to the top of the shorter building is 8°. What equation below will correctly determine the height (h) of the shorter building? A. h = 50 – 200(tan 8°) B. h = 50 – 200(cos 82°) C. h = 50 – 200(tan 82°) D. h = 50 – 200(sin 82°)
