Answer:
The 20 mph headwind slows the plane down. This is because the headwind comes at the head of the plane and goes in the opposite direction of the plane.
So the plane's actual speed (with the wind included) is 550-20 = 530 mph.
Answer:
![\sqrt{125}](https://tex.z-dn.net/?f=%5Csqrt%7B125%7D)
Step-by-step explanation:
Use Pythagorean theorem since you have a right triangle
= ![10^{2} + x^{2}](https://tex.z-dn.net/?f=10%5E%7B2%7D%20%2B%20x%5E%7B2%7D)
225 = 100 +
so x = ![\sqrt{125}](https://tex.z-dn.net/?f=%5Csqrt%7B125%7D)
