By right triangle trigonometry, the sine of the measure of an angle is the ratio of the opposite side of this angle to the hypotenuse.
Thus,
is a constant which can be found using a calculator:
with calc in pc: view → scientific → 27→sin = 0.45399,
thus x=34/0.45399=74.89
Answer: 74.89
Divide both sides by 2 to get x>3
Answer:
D - x = 19 x = -17
Step-by-step explanation:
Factor the equation to make the problem easier - you should have this:
(x - 18) (x + 18) = 1
Set each binomial to 1:
x - 18 = 1
x + 18 = 1
This should give you x = 19 and x = -17

Answer:
and 
Step-by-step explanation:
The function is given as 
<em>to find inverse, we follow the steps shown below:</em>
<em>1. write "y" in place of "f(x)"</em>
<em>2. interchange "x" and "y"</em>
<em>3. solve for the new "y"</em>
<em>4. replace y with f^-1(x)</em>
<em />
Let's do this:
These 2 are the inverse functions.
