X = 25cm , i used pythagoras theorem to calculate this, 7^2 + 24^2 = 625, the square root of 625 = 25
I think the parent function is
y=x
Answer: The answer is the first choice.
Explanation:
Because you must find the sin of the x values in the table.
Sin(7pi/6) = -1/2
Sin(5pi/4) = -sqrt 2/2
Sin(4pi/3) = -sqrt 3/2
