Answer:
False
Step-by-step explanation:
Equation is .2*60=12
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:
This is a convergent geometric series. The sum is 30.
Step-by-step explanation:
In your series, the ratio of terms is 3/5, a value whose magnitude is less than 1. That means the series is convergent. The sum is given by the formula ...
S = a1/(1 -r)
where a1 is the first term (12) and r is the common ratio (3/5). This gives ...
S = 12/(1 -3/5) = 12·5/2 = 30
The series is convergent and has a sum of 30.
