Answer:
125
Step-by-step explanation:
start with 10, and go backwards
10-6=4 4x100=400 400-150=250 250/2=125
checked answer:
125x2=250 250+150=400 400/100=4 4+6=10
Answer:
640.919 feet
Step-by-step explanation:
Given that there is an antenna on the top of a building. From a location 400 feet from the base of the building, the angle of elevation to the top of the building is measured to be 37°. From the same location, the angle of elevation to the top of the antenna is measured to be 40°
Let the height of building be x and that of antenna be y.
Then by considering right angle formed by horizontal line, vertical height and line made by eye contact we have
![tan 37 =\frac{x}{400} \\x=400 tan 37 = 301.422'](https://tex.z-dn.net/?f=tan%2037%20%3D%5Cfrac%7Bx%7D%7B400%7D%20%5C%5Cx%3D400%20tan%2037%20%3D%20301.422%27)
Next considering the height with antenna included we get total height ![=x+y\\=301.422+y](https://tex.z-dn.net/?f=%3Dx%2By%5C%5C%3D301.422%2By)
