Q is congruent to P because they’re both got the same x and y number the x is 5 and -5 and for y is 3 and -3.
We know that
sin²x+cos²x=1
so
clear cos x
cos x=(+/-)√[1-sin²x]
in this problem
<span>Angle 0 is in quadrant 1 -----> cos o and sin o are positive
</span>sin o=2/5
cos x=√[1-(2/5)²]----> cos o=√[1-4/25]----> cos o=√[21/25]---> cos o=√21/5
the answer is
cos o=√21/5
Hi there!
The answer is C. m
The name of a line is always a lower-case letter (e.g. m, k or any other letter from the alphabet).
Answer:
25
Step-by-step explanation:

3 to the power of 2 = 9
so, 16 + 9 is 25...
All I know is the equation is y=12+.75x
