Answer:
Solution 3 is correct and solutions 1 and 2 are incorrect.
Step-by-step explanation:
It says that the parallelogram is reflected across the x-axis. Think of reflection like a reflection in a mirror. The coordinates are mirrored across the x-axis (or the horizontal plane) and the x- coordinates stay the same but the y coordinates change. When you reflect across the y-axis, the x-coordinates change but the y-coordinates stay the same.
I hope this helped!
Its 2 and 5 because 2x5=10
(a)
tanΦ=s/750
Φ=arctan(s/750)
(b)
Φ=arctan(900/750)≈50.19°
Φ=arctan(1500/750)≈63.43°
