Draw a triangle with shortest side on the ground (horiz.). The length of this side is 80 feet. Two angles touch the ground: a right angle, and the 70 degree angle.
Then the height of the building is the 2nd shortest side.
The tangent function is the appropriate one to use here:
opp h
tan 70 deg = -------- = ----------
adj 80 ft
h
Since tan 70 deg = 2.75, 2.75 = -------
80 ft
so h = building height = (80 ft)(2.75) = 219.8 ft
4 I think because you subtract all since it's 60 min
Answer:
9.7
Step-by-step explanation:
First convert the numbers into whole numbers by multiplying both numbers by 100. Then divide the numbers by using long division.
359 because you start with 100, then you multiply 50 x 359 which equals 17950. But then you are the hundred you had to start with to get 18050
