Answer: 6
Step-by-step explanation:
Answer:
I hope this helps you
20 as it is a positive number
use the distance formula
d=_/(x1-x2)^2+(y1-y2)^2
plug the existing values into the formula for your answer. i don’t have a calculator atm so sorry
A' ( 2, 4) and B' ( -4, 0)
A ( -2, 4) and B( 4,0) reflected over the y-axis
the y-coordinate do not change and the x is opposite sign
(x,y) reflected over y-axis (-x, y)
sin(12°)
Because sine and cosine are cofunctions, we can use the relation sin(90° - θ) = cosθ to show that cos(78°) = sin(90° - 78°) = sin(12°)
