Answer:
Step-by-step explanation:
Equation of a line:
The equation of a line, in point-slope form, has the following format:
In which the point is 
and the slope is m.
(3, 20)
This means that 
. So
Slope:
The slope is the derivative of the function at the point:
The function is:
The derivative is:
At the point, we have that 
. So
So the equation to the tangent line to the curve a the point is:

Answer:
e
Step-by-step explanation:
the graph should look something like this
Answer:
∠1 is 33°
∠2 is 57°
∠3 is 57°
∠4 is 33°
Step-by-step explanation:
First off, we already know that ∠2 is 57° because of alternate interior angles.
Second, it's important to know that rhombus' diagonals bisect each other; meaning they form 90° angles in the intersection. Another cool thing is that the diagonals bisect the existing angles in the rhombus. Therefore, 57° is just half of something.
Then, you basically just do some other pain-in-the-butt things after.
Since that ∠2 is just the bisected half from one existing angle, that means that ∠3 is just the other half; meaning that ∠3 is 57°, as well.
Next is to just find the missing angle ∠1. Since we already know ∠3 is 57°, we can just add that to the 90° that the diagonals formed at the intersection.
57° + 90° = 147°
180° - 147° = 33°
∠1 is 33°
Finally, since that ∠4 is just an alternate interior angle of ∠1, ∠4 is 33°, too.
If u need to go from radius to diameter multiply radius times 2: d=2r
