<h3>
Answer: 42.8 feet</h3>
Work Shown:
h = height of the building
h is opposite the reference angle (55)
the adjacent side is 30 feet
tan(angle) = opposite/adjacent
tan(55) = h/30
h = 30*tan(55)
h = 42.84444 which is approximate
h = 42.8 feet
Answer:
The answer is B.36
Step-by-step explanation:
12+12+12=36
12 3x is 3x12
so 3x12 is 36
Let the thickness (or the depth) of the shown figure = t
Total surface area =
=

= 10.6875 + 12.5
= 23.1875
∴ Volume = 23.1875 t
