Answer:
Trigonometric ratios are used to find unknown angles/sides of a right angle triangle
Answer:
.
Step-by-step explanation:
We have been given an expression and we are asked to simplify our given expression.

Using order of operations (PEMDAS) we will remove parenthesis first.
After removing parenthesis our expression will be,

After canceling out 1 with -1 we will get,

So our given expression simplifies to
.
Let us write our expression in standard form. Since our expression is a polynomial and to write any polynomial in standard form, we write each term in order of degree, from highest to lowest, left to right.
Upon putting our polynomial into standard form we will get,

Therefore, after simplifying and putting our given expression in standard form we get our final expression as:
.
Answer:
The correct answer is 2 pi d
Step-by-step explanation:
we know that
the point-slope form of the equation of the line is equal to

so
Step 
<u>Find the slope m</u>
the slope is equal to

Let



Step 
<u>with m and point A find the equation of the line</u>

therefore
<u>the answer is</u>
the point-slope form of the equation is equal to

First
bring the fractions to a like denominator
8/12 equals 2/3 and 9/12 is equal to 3/4
2nd
cut the 8/12 into fourths
so 2/12 each piece
jessica ate 3 of the fourths so she ate
6/12 of the leftovers so it's half of the leftovers
now lets just cut up the pizza into 36. and 2 thirds is equal to 24/36
jessica ate 6/12 so she ate 12/24 of that
jessica ate 1/3 of the pizza
