Please help, I am so confused. If anyone understands this please help

  12 ft

Step-by-step explanation:

It is sometimes helpful to start from what you are given and see what develops.

Here, angle B is 30°. That means angle CAB is 60° (the acute angles of a right triangle are complements). AL bisects that 60° angle, meaning two things:

The side ratios of a 30°-60°-90° triangle are 1 : √3 : 2, so AL is 2 times the length of CL.

  AL = 2 × (6 ft) = 12 ft

We know that AL = LB, so LB = 12 ft.

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
