To find x, you figure out which ratio would be easiest to use.The cosine of the angle (22*) would be x/ll, since cosine is adjacent leg/hypotenuse. Type into a graphing calculator: 11cos(22)
The answer is 10.2. Make sure your calculator is in degree mode!

2. A square is graphed with the vertices at A(-5,-1)A(-5,-1), B(-2,3)B(-2,3), and
gladu [14]

Answer:

25 sq. units

Step-by-step explanation:

Because it is a square, you only have to find one if its side lengths. Let's say you choose to find the distance between B and C. You'll be finding the length of a hypotenuse due to the fact that the two points are diagonal from each other. Use the x and y values to discover the lengths of the legs of the triangle. In this instance, they are 3 and 4. Using background knowledge of the properties of triangles, I know that the hypotenuse of a right triangle with legs of 3 and 4 must be 5. Therefore, the side length of this square is 5. To find the area of a square, simply multiply its side length by itself. 5 x 5 = 25!

Crystal wants to add the fractions 1/16 and 3/18 what is the lowest common denominator of the two fractions?
zhenek [66]

Answer:

288

Step-by-step explanation:

First, simplify the fraction 3/18 to 1/6, this will help a lot. Then, you just, find the LCM, and you can list out the mutliples to help you

6, 12, 18, 24, 39, 36, 42, 48, 54, 60

16, 32, 48, 64, 80

It would be easiest to do 48

But that's not exactly what the question is asking

It's asking the LCM of 1/16 and 3/18

I wanted to show you the other way so you would be able to think of it in a different way which would be easier

You would just list out the multiples again.  

18, 36, 54, 72, 90, 108, 126, 135, 153, 171, 189

16, 32, 48, 64, 80, 96, 112, 130, 146, 162, 178, 194

Ok, I give up on that

Let's just do 16*18 which is 288.

288 is your LCM

Sometimes multiplying is easier and other times listing it out is easier.

I hope this helped
