Answer:
See the proof below
Step-by-step explanation:
For this case we need to proof the following identity:

We need to begin with the definition of tangent:

So we can replace into our formula and we got:
(1)
We have the following identities useful for this case:


If we apply the identities into our equation (1) we got:
(2)
Now we can divide the numerator and denominato from expression (2) by
and we got this:

And simplifying we got:

And this identity is satisfied for all:

This is 90,000 is your answer
325 + 225 + 79 = 629
629 - 438 = $191
= A. $191
Answer:
Step-by-step explanation:
Let the total amount ate by Tyler and Han be 24
Let the amount Tyler ate be x
Amount Han ate be y
If Tyler ate 3/4 of the total, then Amount ate by Tyler is expressed as;
x = 3/4of 24
x = 3/4×24
x = 3×6
x = 3(6)
x = 18
Hence the amount Tyler ate is 18
If Han ate 18 less than Tyler, the amount ate by Han will be;
Han y = 24-(3/4(24)
y = 24-{3(6)}
y = 24-18
y = 6
Hence the total Han ate is 6
The answer to this question is:
9x+8/3x^2
