Answer:
50 degrees.
Step-by-step explanation:
Angle FGE =
because angles on a straight line add up to 180 degrees.
Angle EFG =
(Angles in a triangle add up to 180)



Add 20 to both sides:


Subtract 6x from both sides:


Angle 
ANSWER
D.

EXPLANATION
The standard equation of the hyperbola is

We multiply through by 36 to obtain:

We now expand to get,

Expand :

To get the general form, we equate everything to zero to get,

The correct choice is D.
Answer:
7.2
Step-by-step explanation:
To reach point D from point C, you need to add 4 to the x-value of point C and take away 6 from the y-value. These numbers are the sides of the hypothetical triangle.
The Pythagorean Theorem states that
. If we plug the side lengths in for a and b, we get
. This can be simplified to
, or
. If we root both sides, we find that c is equal to
, which is slightly more than 7, at around 7.2.
