1. x= 3/Y as a fraction btw
2. Same thing
Answer:
<em>D. In a parallelogram, opposite angles are congruent.</em>
Step-by-step explanation:
In each case, she measures two opposite angles, and they are congruent.
D. In a parallelogram, opposite angles are congruent.
Do you need to show your work ?
as the exterior angle is known
sum of that angle and f angle = 180
142 + f = 180
f = 180 - 142
f = 38
Without knowing anything else about 
, neither of these need be true.
Suppose
Then (I) isn't true because, while the limit exists as 
and is equal to 7, we have 
, so is not continuous there.
(II) also true because is not differentiable at 
; that is,
but
which means the derivative does not exist at .
