Hope it's helps you
First angle 90 degrees
Second angle 30 degrees
Third angle 60 degrees
We have question

<span> /*8 (multiply both sides by 8)</span>

/*6 (multiply both sides by 6)

/-30 both sides
8W=-66-30
8W=-96
W=-12
The answer is D. 2+1/5×(7/12+3)
The velocity of the particle is given by

Since
and
, we get


Similarly, the position function is obtained via

We know
and we're told that
, so


making the answer A.
