Ts A. Congurent only denotes something being of the same shape and size, so if one wouldn't right and the other wasn't they wouldn't be identical, which is what its about.
Answer:
Period =½
Equation of midline, y=0
Maximum =2
Minimum=-2
Step-by-step explanation:
The given function is

The period is given by:

The equation of the midline is y=0 since there is no vertical shift
The amplitude of this function is 2 so the range is -2≤y≤2.
Hence the maximum value is 2 and minimum value is -2
Answer:
The answer is 63°
Step-by-step explanation:
The lines intersect so opposite angles are congruent.
The answer is 1,2,4,6,8 because the circle has a circumference of 9
