<span>A. tan Y= y/z
Just remember the three major identities for trig with a right triangle.
sin Î¸ = opposite/hypotenuse
cos Î¸ = adjacent/hypotenuse
tan Î¸ = opposite/adjacent
And in the diagram, the opposite side to Y is y and the adjacent side is z. So the tangent is y/z which matches option "A" from your choices.</span>

By definition you have that the tangent of an angle in a right triangle is given by the quotient between the sine of the angle and the cosine of the angle.
Since we know how much the sine and the cosine measure (we have the sides of the triangles as data), then the tangent is given by:
A. tan Y= y/z
answer
A. tan Y= y/z

Nimisha wants to draw a wheel like the one shown. Each shaded part of the wheel should be one-third of each unshaded part. What

ivolga24 [154]

Answer:

Each shade has a 22.5 degree angle from the middle

Each unshaded has a 67.5 degree angle from the middle.

Step-by-step explanation:

You can solve this by making each unshaded part equal to x and each shaded part equal 1/3x it is a circle so it has to equal 360 so you end up with:

x + 1/3x + x + 1/3x + x + 1/3x + x + 1/3x = 360

Combine Like terms:

16/3x = 360

Multiply both sides by the opposite:

(3/16) (16/3x) = (360) (3/16)

x=135/2 or x=67.5

Then you can plug 67.5 in for x:

1/3x ---> 1/3(67.5) = 22.5

Help with 6 a and b please

34kurt

Answer:

a) $y=\frac{50}{x}$

b) $y=25$ when $x=2$

Step-by-step explanation:

$y=\frac{k}{x}$ since y varies inversely with x.

We need to find the constant, k.

Let's use a point (x,y) on the curve.

We are given an (x,y)=(5,10):

$10=\frac{k}{5}$

Multiply both sides by 5:

$10(5)=k$

$50=k$ .

So the equation is:

$y=\frac{50}{x}$

What is y when x=2?

$y=\frac{50}{2}$

$y=25$

Express the decimal as a percent. 0.053

velikii [3]

Hey this is very easy to learn! So to express a decimal as a percent all we have to do is multiply it by 100. So multiplying .053 by 100 would just mean moving the decimal point 2 spaces to the right.

So the answer would be 5.3%

I hope this helps!
