There are 2 ways that spring to mind.
One is to use the definition of the derivative at a point:
In this case, 
and 
. Then
- - -
If you don't know about derivative yet (I would think you do, considering this is for a midterm in AP Calc, but I digress), the other way is to rely on algebraic manipulation. Multiply the numerator and denominator by the conjugate of the numerator to get
This is continuous at 
, so the limit is the value of the expression at :
Answer:
Y=30
Step-by-step explanation:
D+E+F+G=360
D+F=360-106-84=170
D+F=Q+S
Y+38+3Y+12=170
4Y=170-50=120
Y=30
X=4 ..............................

The complete question is missing, so i have attached it.
Answer:
x = 9(sin 42)/(sin 29)
Step-by-step explanation:
We want to find an expression for x.
From the attached image, we can see a triangle with 2 angles given and 2 sides to be 9 and x respectively.
Now, the law of sines says that;
A/sin A = B/sinB = C/sin C
So applying it to this question, we have;
x/sin 42 = 9/sin 29
Thus,
x = 9(sin 42)/(sin 29)
