Multiply both sides by 2.54.
Multiply both sides by x.
x = 60.96
Hence, Aaron needs 60.96 centimeters of wire.
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
Number of possible combinations = (4x3) ÷ 2 = 6
Answer: There are 6 possible combinations.
1-1=0 lol how do u not know this ???
