Answer:
0.034921 miles or 1843774 feet tall
Step-by-step explanation:
Using trigonometric functions we know that
and
where
=angle and r is the hypotenuse of the triangle.
First we will calculate the hypotenuse using the x equation, since we know x = 1 mile (distance from the building on the ground) we have:

Now we will calculate the height of the building using the y equation and so:

The building is 0.034921 miles or approximately 184.3774 feet tall.
This is a geometric sequence with common ratio (r) = 2.
an = ar^(n - 1)
a4 = a(2)^(4 - 1) = a(2)^3 = 8a
8a = 80
a = 80/8 = 10
7th term (a7) = 10(2)^(7 - 1) = 10(2^6) = 10(64) = 640
m < 6 = m < 2 because they are corresponding angles
So m < 6 = 113 degrees answer
56/90
" / " means divide
56 divided by 90 = 0.62 with a line over the 2 because it is repeating
Answer:
As shown in picture, we have

Hope this helps!

Explanation:
Let say right triangle ABC has A = 90 deg.
=> BC is hypotenuse.
=> BC = AC x BC/AC = AC/(AC/BC) =AC/cosC.
That's the way we've done!
