Step-by-step explanation:
25^(4x) = (25^4)^x = (5^8)^x = 5^(8x).
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!
478×427= 204,106cm
204,106cm - 2041.06m
204,106cm - 20.411m2
I believe the answer is 1/3
