So you need to use the inverse tan to find the measure of angle c.

So since tan is opposite over adjacent.

You get the inverse tan of 6/8. And you get 36.87 degrees.

Answer:

20%

Step-by-step explanation:

Well, it's actually relatively simple.

The first thing to do would be to write this in a fraction form. You payed 72,000 out of 360,000.

72,000/360,000.

now you take that fraction, and convert it's to its decimal form which will give you a 0.2.

0.2 in decimal form is converted to 20.0% (when you convert a decimal to a fraction, you multiply by 100, or move the decimal two places to the right).

Another way to do this is simplifying the fraction.

take 72,000/360,000 and find what X is when

72,000/360,000 = x/100

you will find that 72,000/360,000 Is equal to 20/100. since percents are calculated as out of a hundred. your answer would still come out as 20%

V=πr^2h<br> solve for r<br> r=

egoroff_w [7]

To solve for r, you just need to isolate r. To do that, divide by h and π on both sides:
$\frac{V}{h \pi }=r^2$

Then, square root both sides to get rid of the 'squared':
$r = \sqrt{ \frac{V}{h \pi } }$

Or, if you wanted the answer in terms of π, then just don't divide by it, just divide by h and then square root it.

If f(x)=x/2-2 and g(x)=2x^2+x-3, find (f+g)(x)

Lelu [443]

Hello :
<span>If f(x)=x/2-2 and g(x)=2x^2+x-3, find (f+g)(x)
</span>(f+g)(x)= f(x) +g(x) = x/2-2 +2x²+x-3 = x/2 +2x²+x-5
(f+g)(x)= (x+4x²-2x-10) /2
(f+g)(x)= (4x²+3x-10)/2 = 2x²+3/2 x -5

The diagonals of a rhombus bisect each other of measures 8cm and 6cm .Find its perimeter. please help !!!!!!!!!!!!!!!!!!!!!!!!

Delvig [45]

Answer:

20 cm

Step-by-step explanation:

8/2 = 4

6/2 = 3

3 and 4 are the sides of the triangle (four triangles in rhombus)

$a^{2} + b^{2} = c^{2} \\4^{2} + 3^{2} = c^{2}$

c = 5

5 x 4 = 20

Hope that helped!!! k
