Is it -227? I know that it's in quadrant 2 and the reference angle is 47 degrees and Tan -227 shares both of these with Tan 133. Both of them are -1.07236971 because Tan is negative in Q2. But I am confused about the "same sine value" part of the question.

sin 31 = opposite / hypotenuse = height / 65     

I still don't know what you are talking about.

"REDA REDB is one hand of two cards. "

How is this one hand of two cards.  There are 2 lots of 4 letters here.  It makes no sense.

Thanks for responsing though.  I gave you are point just for responding.

What is the $ sign for?

Your question is also rubbish.

So I suppose it is a  reasonable answer.      Garbage in, garbage out.

What quadrant is 133 degrees in?

Is tan pos or neg in this quadrant? 

Which other quadrant has the same sign?

What is the acute angle equivalent of 133 degrees?

So what is the answer?

Get back to us with what you can do for yourself.

I meant: Thanks man, but it is wrong.

The hypotenuse of a right isosceles traingle is 6 cm long. Write an exact expression for Sin X, Cos X, and Tan X. (X = angle)  

Since it's a right isosceles triangle, each leg is (6 / sqrt(2))  =  (6 • sqrt(2)) / 2   =   3sqrt(2)  

sin = opp / hyp  =  (3sqrt(2) / 6)  =  (sqrt(2) / 2)  =  0.7071  

cos = adj / hyp  =  (3sqrt(2) / 6)  =  (sqrt(2) / 2)  =  0.7071  

tan = opp / adj  =  3sqrt(2) / 3sqrt(2)  =  1.0000

You should rather say thanks. 

Also when it's wrong or right.

The reflection is (-1/10, 57/10).

The quadratic is 5x^2 - 3x + 12

f(1) = 12.

\(PQ = \boxed{\frac{50 \sqrt{2}}{7}}\)

The answer is 30, and it can be found here: https://web2.0calc.com/questions/halp_104

Express this problem as 2 right triangles. The first one has a base of 24, and by doing \(24 \over cos (35)\), you find that the Hypotenuse is 29.3 meters long. By doing \(29.3 * sin(35)\), you find that the height of the triangle is 16.8 meters long. By doing the same to the other triangle, you find that the height is 24.8 meters. Now, by using the Pythagorean's theorem, \(48^2 + 8^2 = x^2\), you find that the distance between the treetops is 49 meters. 

When graphed, the triangle looks like this:

The triangle has a height of \(8 \over 5\) and a base of \(16 \over 3\). This means that the area of the triangle is \({{{8 \over 5} * {16 \over 3}} \over 2} = {4 {4 \over 15}}\).

A: City D is \(1/2 * 12\)

B: This means that City D is positive \(6\) feet above sea level, 

Assume the DVD costs \(d\), For the first option, you would only pay the cost of one \(d\). For the second option, you would pay the cost of \(d + 0.75d\), because the first one costs \(d\), and the second one costs \(0.75d\). Thus, the first option is the better deal. 

GA,

I am only 13 and don't smoke.

Interesting story though.  :)

I am refering to Web2.0calc being free to use!

For the first option, you pay $75.65:

89 = 100

8.9 = 10

4.45 = 5

13.35 = 15

For the second option, you pay $93 - 20, so $73. 

Thus, the second option is the better deal.

Thank you all for helping me out.  :)

Thanks to Alan as well for doing the problem out.  ;)
