Answer:
Step 4, because there is only 1 conversion needed.
Step-by-step explanation:
To convert pounds to kilograms, one only needs to divide by (2.2 pounds/kg). That was done in Step 3, so no further steps are needed.

Answer: 15
Step-by-step explanation:
=(−5−4)2+(−4−8)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√
d=(−5−4)2+(−4−8)2
=(−9)2+(−12)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾√
d=(−9)2+(−12)2
=81+144‾‾‾‾‾‾‾‾‾√
d=81+144
=2‾√25
d=225
=15
To find x we can use that fact that x is in the adjacent side of the 22° angle. We also know that 11 is our hypotenuse. Now, we can use trigonometry to find x.
cos(Ф)=adjacent/hypotenuse
cos(22°)=x/11
11 · cos(22°)= x/11 · 11 multiplicative inverse
11 cos (22°)=x
10.2≈x
Alternate interior angles on parallel lines via the parallel postulate gives you the angle supplementary to x = 120°, so x = 60°. alternate interior angles on 70° via the parallel postulate gives you y = 70°
