Answer:

12.30

Step-by-step explanation:

Soh Cah Toa

You know the angle, and the opposite. You want to find the adjacent. So you will you Toa.

tan(°) = O/A

tan(26°) = 6/A

Rearrange to get A on its own.

Atan(26°) = 6

A = 6/tan(26°)

A = 12.301 = 12.30 (2dp)

What is 15% of $10.00

Katarina [22]

In mathematics, the word 'of' always means multiplication, so to find out what 15% of $10.00 is, all we need to do is multiply the percentage by the dollar amount we are reducing.

In order to do this, we must first convert the percentage into a decimal. To do this, we can either divide the percentage by 100, or (my personal shortcut) just shift the decimal point over two places to the left.

15% = 0.15

So now, we can multiply.

0.15 * 10 = 1.5

which is our answer.
15% of $10.00 is $1.50.
Hope that helped! =)

How can I find the unknown side lengths when given the area or circumference of a figure?

ad-work [718]

Answer:

Set up the area/circumference equations using x as the unknown variable. Then, solve for that variable and apply the correct unit.

Step-by-step explanation:

For example,

Find the side length of a square with an area of 49 square centimeters.

Since $area=s^{2}$ , i can write $49=s^2\\then take the square root of each side to solve for s.\\s=\sqrt{49} \\s=7 centimeters$
