Answer:
34°
Step-by-step explanation:
The angle formed by two tangents is equal to half the difference of the intercepted arcs.
The first intercepted arc, between points A and C, is 146°. This leaves
360-146 = 214° for the second intercepted arc.
The difference between these two is
214-146 = 68°
Dividing this by 2,
68/2 = 34°
Given:
The pair of expressions in the options.
To find:
The two expressions are equivalent for any value of y.
Solution:
Two expressions are equivalent for any value of y, iff they are equivalent.


Clearly,
is not equivalent to
or
. So, options A and B are incorrect.



The expression
is not equivalent to
. So, option C is incorrect.
The expression
is equivalent to
.
Therefore, the correct option is D.
Answer:
point B is (0,1)
Step-by-step explanation: A and the midpoint are 4 units away right so count out B and you get (0,1)
You have to get x alone and then do the rest of the steps
