Law of sines anyone? ? need good explanation..ill give brainlest

Step-by-step explanation:

So i will try to explain it:

Scientists in the past invented this formula and theory of sines:

So the only thing is to put the given numbers into this formula :)

The task that i've just done is like this:

a is the numerator,that is delighted in the triangle,well its transparent.

What about denominator?

Here is the tip:

opposite to A- side angle-a has to be put into sin(a)

sin- how to calculate?

Easy just take the trigonometric functions formula or calculate in scientific calculator that's it.

one of this numbers might be unknown in that case solve by proportion(equation).

Carefully contemplate my answer in the media.

I hope you understood.

Good luck!

answer: can and shows the work

step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
