Answer:
19
Step-by-step explanation:
16+3=19 the key word total means you add
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:
there is not a complete question here ...
is not in a denominator to rationalize
if it were you would multiply the rational expression (the fraction)
by 
the result (in the denominator would end up being "2 -1"
which is 1
Step-by-step explanation:
Answer:
Area of A = 32ft
Area of B = 36ft
Step-by-step explanation:
All you need to do to solve is multiply width * length * height.
If you do so,
Area of A = 3 * 2 * 5 1/3
= 6 * 16/3
= 32
Area of B = 6 * 4 * 1 1/2
= 24 * 3/2
= 36
