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
Answer: It would be B, 200%
Step-by-step explanation:
144/3 = 48
48/24 = 2
48/0.24%= 200%
Answer:
1 kilometre =
100000 centimetres
( convert into cm )
formula = multiply the km value by 100000
( convert cm into km) = divide by 100000
Answer:
$69.60
Step-by-step explanation:
20% of $58 is $11.60. So you add $11.60 + 58 which equals $69.60, so that is the total cost.
