Answer:
= 78
= 3.5
Step-by-step explanation:
First we need to find
.
We can use the equation
to solve for
.
We can then change that equation to
, since the Commutative Property of Addition says that you can have any addition in any order.
Now, we can solve the equation.

Now that we solved
, we can now solve for
.
Since 25 equals
, we can solve the equation
.
Here is how you solve it:

Since
equals 3.5, which is the simplest form, that is the answer.

Answer:
We can write sin 21° as 1200 / x and also 0.36 so we can write:
1200 / x = 0.36
1200 = 0.36x
x = 1200 / 0.36
x ≈ 3333 ft
