This is an angle of elevation problem. So, we use the tangent ratio.
tan84=x/150
this then becomes
x=150(tan84)
which simplifies to
150∗(tan84)=1427
Since she only begins to observe the building 5 feet higher than where it starts, we add 5+1427, so your final answer is 1432 feet tall!
Answer:
4x^2+20x+25
Step-by-step explanation:
(2x+5)^2 = (2x+5) (2x+5)
Using the foil method : 2x(2x) = 4x^2
(2x) (5) = 10x
(2x) (5) = 10x
5 (5) = 25
