The answer is 37.5

THe answer is seven

Base times t=heith divided by 2 equals area

Well, it helps us do many things, like build things and it helps with science, measuring and a lot more.

The Answer to thy question equals 7.

I'm not sure I understand the question....could you give us a specific problem???

We know an an angle, a hypotenuse - the ladder length - and we're looking for an adjacent side. The cosine function seems appropriate....so....

cos 55= adj / 24   multiply both sides by 24

(24) cos55= adj = about 13.77 ft from the wall

V = s³   where s is the side length

13.8564i to 4 decimal places and where i is the square root of minus 1.

x = 2 implying y = 0 is ok. but x = -2 leads to a contradiction.

Also, the equations are symmetric in x and y, so it's possible to switch the x and y values to obtain a second solution corresponding to x=2, y=0.

An alternative method of solution would be to square the second equation and then combine that with the first leading to 2xy = 0, from which either x = 0, or y = 0.

Then substitute into the second equation, (not the first), to find the corresponding y or x value.

It depends on what information you have regarding it. The lengths of all three sides, the lengths of two sides and the included angle, two angles and the length of the included side, base length and height. Which ?

What do you mean by symmetrical ?

Solve the equations simultaneously.

Substitute the y from the first equation into the second and solve the resulting equation for x. Put that value back into the first (preferably), or second equation to find the corresponding value of y.

Then what ? We wait with bated breath.

On the assumption that alpha, beta, a and b are real,

$$\alpha -\imath \beta=\frac{1}{a-\imath b}=\frac{a+\imath b}{a^{2}+b^{2}}.$$

Taking the complex conjugate of both sides,

$$\alpha + \imath\beta=\frac{a-\imath b}{a^{2}+b^{2}},$$

and multiplying the equations together,

$$\alpha^{2}+\beta^{2}=\frac{a^{2}+b^{2}}{(a^{2}+b^{2})^{2}},$$

from which the result follows.

The Answer Is 55.

Lol.

Same with me, questions worded like this make my brain explode!

Too much to take in!!!

4x4 is 16.

I think you either forgot to mention some of the details, or the variables (other than i off course) have an implicit meaning which I'm unaware of. 

Anyway, I can make it a little easier for you by doing the following. 

$$\begin{array}{lcl}
\alpha - i\beta &= \frac{1}{a-ib}\\
\alpha - i\beta &= \frac{1}{a-ib}\frac{a+ib}{a+ib}\\
\alpha - i\beta &= \frac{a+ib}{a^2+ aib - aib -i^2b^2}\\
\alpha - i\beta &= \frac{a+ib}{a^2+b^2}\\
(\alpha - i\beta)(\alpha + i\beta) &= \frac{(a+ib)(\alpha + i\beta)}{a^2+b^2}\\
\alpha^2 +i\alpha \beta - i\alpha \beta - i^2 \beta^2 &= \frac{(a+ib)(\alpha + i\beta)}{a^2+b^2}\\
\alpha^2 + \beta^2 &= \frac{(a+ib)(\alpha + i\beta)}{a^2+b^2}\\
(\alpha^2 + \beta^2)(a^2+b^2)&= (a+ib)(\alpha + i\beta)
\end{array}$$

 Now if you can prove that

$$(a+ib)(\alpha + i\beta) = 1$$

You're there.

Reinout

do you mean adjacent divide by hypotenuse

89.55432 is the answer

sine (sin)=opposite/hypotenuse

cosine (cos)= adjacent/hypotenuse

you dont , you chicken

There are 36 possibilities when two dice are rolled.

The ways to make a 10 are

4 - 6

6 - 4

5 - 5

So the probability is  3/36 = 1/12
