Answer:
Part 1) The length of two sides and the measure of the included angle (Side-Angle-Side)
Part 2) 
Part 3) 
Step-by-step explanation:
we have
In the triangle ABC
Part 1) Which information about the triangle is given?
In this problem we have the length of two sides and the measure of the included angle (Side-Angle-Side)
see the attached figure to better understand the problem
Part 2) Which formula can you use ti find b?
I can use the law of cosines
we have
substitute the given values
Part 3) What is b, rounded to the nearest tenth?
Remember that
To Round a number
a) Decide which is the last digit to keep
b) Leave it the same if the next digit is less than 
(this is called rounding down)
c) But increase it by 
if the next digit is or more (this is called rounding up)
In this problem we have
We want to keep the digit
The next digit is 
which is 5 or more, so increase the "5" by 1 to "6"
therefore
Answer: ?=7
Explanation: Use pythagorean theorem
Answer:
B, C, D, & E
Step-by-step explanation:
All lines intersect the x axis and y axis so we know B and D are correct. All graphs are in the xy plane unless i (
) is involved, or C. It crosses the center (origin) of the entire plane so it crosses the origin, or E.
Step-by-step explanation:
tan (0)=sin (0)/cos (0)
cos (0)=sin (0)/tan (0)
= -4/5/4/3
= -3/5
Answer: y+9=-2(x-9)
Step-by-step explanation:
The point-slope equation is 
. All we have to do is fill in all the values except for y and x.
To find m, you use 
. Since we are given 2 points, we cna plug them in.
. Now that we have our slope m, we can fill in the point slope equation.
