That triangle's upside down but the usual rules hold.
We know the side opposite the 39 degree angle is 10 m and we're asked for the adjacent side. The unlabeled side is the hypotenuse.
That's tangent:


Answer B
Answer:
HC=
Step-by-step explanation:
Let HC=x, it is given that AH=3HC, then AH=3x.
Since, from the given figure, ΔABC is similar to ΔBHC and ΔABC is similar to ΔABH.
Therefore, ΔABH is similar to ΔBHC, hence using the similarity conditions,





Hence, HC=
.
If the arrow is in the air, then when it hits the ground, h(t)=0. So:
0=-16t²+63t+4
16t²-63t-4=0
(16t+1)(t-4)=0
t= -1/16 or 4
Using the positive result of 4, we get t=4 seconds as the time the arrow was in the air
