Answer:
the first three are the answer
Step-by-step explanation:
X=8.5
190-5=185
185/-5=-37
-37-3=-34
34/4=8.5
Answer:
The answer is b : translate K to N and reflect across the line containing JK
Step-by-step explanation:
I just took the quiz
The cofunction of cos is sin(90-x)
90 degrees is equal to PI/2
The cofunction becomes sin(PI/2 - 2PI/9)
Rewrite both fractions to have a common denominator:
PI/2 = 9PI/18
2PI/9 = 4PI/18
Now you have sin(9PI/18 - 4PI/18)
Simplify:
Sin(5PI/18)
