Answer:
Step-by-step explanation:
we know that
The formula to calculate the area of a triangle applying the law of sines is equal to
we have
substitute in the formula
If a polynomial has three terms, x2 + 12x + 36, which factoring method can be considered?

A) Pine Road and Oak Street form a right angle, so we can extract the relation
where
is the distance we want to find (bottom side of the rectangle).
Alternatively, we can use the other given angle by solving for in
but we'll find the same solution either way.
b) Pine Road and Oak Street form a right triangle, with Main Street as its hypotenuse. We can use the Pythagorean theorem to find how long it is.
Let
be the length of Main Street. Then
but of course the distance has to be positive, so
