You are the coach of a basketball team. So far this season, you have collected the following statistics showing how many points
krok68 [10]
<span>You are given the following statistics showing how many points each player scores on average and how many points the team scores in a game when the player is not playing.

Player A PPG: 25 Team Points
when the player is absent: 100
Player B PPG: 24 Team Points
when the player is absent: 80
Player C PPG: 20 Team Points
when the player is absent: 84
Player D PPG: 19 Team Points
when the player is absent: 87
Player E PPG: 13 Team Points
when the player is absent: 50
Player F PPG: 5 Team Points
when the player is absent: 99
Player G PPG: 5 Team Points
when the player is absent: 90

(1) The player that is most helpful to the team is Player A. When player A is playing,he can garner 25 points and when he is not around, the team loses 100 points.
(2) The player that is the most altruistic (helpful to others) is Player E. Even if he can just gain 13 points when playing, when he is not around, their lost is just 50 points.
(3) The order from increasing to the least is player A, B, D, C, E, G, F.</span>

A palm tree is supported by two guy wires as shown in the diagram below. Which trig expression can be used to find the height on
Volgvan

Answer:

D. tan(30^\circ+45^\circ) is the correct answer.

Step-by-step explanation:

The given situation can be represented as a figure attached in answer area.

B is the base of tree.

C is the base of wires.

A and D are the end of 2 wires supporting the tree.

\angle DCB =45^\circ\\\angle ACB =75^\circ\\

Here, we need to find the Height of the tree which is represented the by side AB.

and we are given that bases of wires and tree base are at a distance 4 ft.

i.e. side BC = 4 ft

If we look at the \triangle ABC, we are given the base BC and the \angle ACB, and the perpendicular is to be find out.

We can use trigonometric identity:

tan\theta =\dfrac{Perpendicular}{Base}

tan 75^\circ = \dfrac{AB}{BC}\\\bold {tan (45+30)^\circ }= \dfrac{AB}{4}\\\Rightarrow AB = \bold {tan (45+30)^\circ } \times 4 = 14.93\ ft

Hence, D. tan(30^\circ+45^\circ) is the correct answer.
