Answer:

15/2 sqrt(3) =z

15/4 sqrt(3) =y

Step-by-step explanation:

cos theta = adjacent side/ hypotenuse in a right triangle

cos 30 = z / 15

Multiply each side by 15

15 cos 30 = z

15 ( sqrt(3)/2)

15/2 sqrt(3) =z

sin theta = opposite side/ hypotenuse in a right triangle

sin 30 = y / z

Multiply each side by z

z sin 30 = y

z (1/2)=y

Z = 15/2 sqrt(3)

15/2 sqrt(3)*1/2

15/4 sqrt(3) =y

How would I solve this equation by showing my worki on each side?<br> X divided by 10= 7
Sav [38]

Answer:

x=70

Step-by-step explanation:

x/10=7

First you need to get the x by itself, so you should do the opposite of what is happening to the x.

In this case the x is being divided so you would need to multiply.

So multiply the x by 10 and this gets it by itself.

But you have to do to one side what you do to the other.

So multiply the other side by 10 as well!

This equals x=70

To show work on both sides, show the multiplication of both sides by 10

Allison bought some shirts for he clothing store for $15 each. She received $50 off her entire purchase and spent a total of $40
k0ka [10]

The $50 off was like a coupon after you brought all your merchandise to the counter, so we have to add it back in to determine the number of shirts.

$400+$50=$450 original price of shirts

Original price ÷ price per shirt= quantity purchased

$450 ÷ $15/shirt= 30 shirts purchased

Allison bought 30 shirts.

Hope this helps! :)
