If we simply substitute the value x=2 in the expression we have
which is undefined.
But if we factor both numerator and denominator, we have
Since we are studying the limit as x approaches 2, we can assume that x is not 2. In this case, we can simplify the (x-2) parenthesis, and the expression becomes
And we can evaluate this at 2 with no problems:
So, we have
This means that in this case both left and right limits exist and are the same, so the limit exists, but the function is not defined at x=2. This is a removable discontinuity, because we can define the function as its limit, and we have a continuous function at x=2:
Answer:
When we know all 3 sides we use the law of cosines
a = 47
b = 11
c = 38
cos (A) = (b^2+c^2-a^2) / (2bc)
cos (A) = -0.7703349282
Angle A = 140.38
cos (B) = (a^2 + c^2 -b^2) / (2ac)
cos (B) = 0.9888017917
Angle B = 8.5826 degrees
cos (C) = (a^2 + b^2 -c^2) / 2ab
cos (C) = 0.8568665377
cos (C) = 31.033 degrees
Angle W would be the smallest angle so it equals
31.033 degrees or rounded to nearest tenth
31.03

Given.
Sally started with two feets of cloth.
Total cloth =
She used of a foot of the cloth to make a pillow cover.
And another of a foot of the cloth to make a table cloth.
She used total cloth to make a pillow cover and table cloth =
Total used cloth by Sally =
The equation for remaining cloth
remaining cloth = total cloth - used cloth
remaining cloth
remaining cloth
remaining cloth
remaining cloth
Sally has remaining cloth = feets
