Need DESPERATE help! I'm taking a unit test for math (k12, 10th grade) I got 3 done already so here's the ones I missed: Questio
wlad13 [49]

Answer:

Step-by-step explanation:

Question 6)

sin Y= m

sin Y = m/1

So, hypotenuse is 1

Since sine is opposite over hypotenuse

So XZ= m and YZ = 1

Similarly, cos Y = k

cos Y = k/1

So adjacent side of angle Y is k

So XY = k

cos z - sin z = \frac{XZ }{YZ } - \frac{XY}{YZ}

cos z - sin z = \frac{m }{1 } - \frac{k}{1}

cos z - sin z = m - k

Question 7)

the relationship between sine, cosine, and tangent.

tan(x) = sin(x)/cos(x) = (11/61)/(60/61)

tan(x) = 11/60

Question 8)

Start with where the shorter leg is. It must be opposite the smallest angle.

In a 30 - 60 - 90 degree triangle you have the hypotenuse to be twice as long as the shortest side. You have to read that a couple of times to make sure you understand it. 

That being said, if the shortest side is x, the hypotenuse will be 2x.

Since in this case the shortest side is 11, the hypotenuse will be 2*11 = 22

The answer is 22

Use 3.14 for PI( π ) <br><br> Diameter: 5 ft <br> Formula: A= πr2
Liula [17]

Answer:

\boxed {\boxed {\sf 19.625 \ ft^2}}

Step-by-step explanation:

The area of a circle is found using this formula:

a= \pi r^2

We know the circle's diameter is 5 feet, but we don't know the radius. Remember the diameter passes through the center from one side to the other, while the radius connects the center and the side. Therefore, the radius is half the diameter.

  • r=d/2
  • r= 5 ft/2
  • r= 2.5 ft

We know the radius is 2.5 feet and we are using 3.14 for pi. Substitute the values into the formula.

a= (3.14)* (2.5 \ ft)^2

Solve the exponent.

  • (2.5 ft)²= 2.5 ft *2.5 ft=6.25 ft²

a= (3.14)*(6.25 \ ft^2)

Multiply.

a=19.625 \ ft^2

The area of the circle is <u>19.625 square feet.</u>
