Building
To the nearest foot, what is the height of the building?
A. 239 ft
B. 154 ft
C. 67 ft
D. 33 ft
​

Answer 1

For this you are using tangent, opposite over adjacent. Tan64°= X/75.The 75 on the bottom means X is being divided by 75. So we multiple each side by 75 to get 75xtan64°= x. when you put that in a calculator you get 153.77 ft. Which is closer to 154, answer B
