Answer:
16.49
Step-by-step explanation:
21^2 - 13^2 = 272
square root 272 = 16.49
Remark
I'm going to interpret this equation as
D = ut + kt² The only difference is the 2.
Solution
Subtract kt² from both sides.
D - kt² = ut Now divide by u on both sides.
The t's cancel out. on the right. You are left with u on the right.

Answer:
the third one
Step-by-step explanation:
the third one
Tan of an angle = perpendicular / base
<span>Here, perpendicular is the side of the triangle opposite the angle. </span>
<span>And base is the arm of the angle other the hypotenuse. </span>
<span>If the side of the triangle to be found (marked as ? in the figure) is x, then </span>
<span>perpendicular = 20 feet </span>
<span>base = x </span>
<span>so, tan 30 = 20/x </span>
<span>so, x = 20/(tan 30 degrees) = 34.64 feet </span>
<span>= 35 feet to the nearest foot</span>
