=
[by using the laws of indices]
All other steps are correct.

All other steps are correct.
Answer:
B
Step-by-step explanation:
Since the triangle is right use the tangent ratio to find x
tan22° =
= 
Multiply both sides by x
x × tan22° = 203 ( divide both sides by tan22° )
x =
≈ 502.5 m → B
Not reasonable, there are 100 pennies in a dollar so the actual equation is 100d
2x5= p divided by 3
2x5=10
10÷3=3.33
so it is 3 1/3
