I know for a fact that the reference angle for 3pi/2 is pi/2 so the first one is A, and if I'm not mistaken, the second one should be undefined. I'm not sure about the second one.
Answer:
± 2
Step-by-step explanation:
let the number be n , then
n² - 4 = 0 ( add 4 to both sides )
n² = 4 ( take square root of both sides )
n = ±
= ± 2
The number is - 2 or 2

Answer:
The answer would be Choice F; (-3,7)
Step-by-step explanation:
- Plot the two guaranteed given points
- A, (-3,2) and C, (2,7)
- Find the point where the x and y would share and then form a right angle. This is called being Perpendicular.
- So, take the <em>x</em> of A, and the <em>y</em> of C and you have the coordinates of B.
(-3,7)
