Answer:
100
Step-by-step explanation:
start with what's in the parenthesis':
8 (9.75 - 3.25) + 12 x 4 = 8 (6.50) + 12 x 4
then take the number outside of the parenthesis' time the number inside of them:
8 (6.50) + 12 x 4 = 52 + 12 x 4
now, take the product of the two number on the right side of the addition sign:
52 + 12 x 4 = 52 + 48
finally, add the final two numbers together:
52 + 48 = 100
It is 4.5 away from the Y axis and 2.25 away from the X axis.
Answer:
A. Building A, it is around 100.69 feet taller than building B.
Step-by-step explanation:
Since building A is 120 feet away at and elevation of
, then:
Tan
= 
Where x is the height of the building at the horizontal plane.
x = Tan
× 120
= 100.692 feet
For building B at the same elevation,
Tan
= 
x = Tan
× 60
= 50.346 feet
Since the angle of elevation are the same, building A is around 100.69 feet taller than building B.
