Answer:
Therefore the game board is divided into 81 smaller squares.
Step-by-step explanation:
Given that, there is a square game.
Consider x be length of one side the square.
The volume of the square is = side ×side
=x² square units
Since the length of side of smaller square is one-ninth of the game board.
Then one side length of the smaller square is 
units.
The area of a smaller square is 
Let a number of square is formed from the game board.
a ×The area of one smaller square= The area of game board.
According to the problem,
Therefore the game board is divided into 81 smaller squares.
X is in the second quadrant means that x/2 is in the first quadrant.
Consider the right triangle drawn in the figure. Let tan(x/2)=a.
Then, let the length of the opposite side to x/2 be a, the adjacent side be 1 and the hypotenuse be square root of a squared +1, as shown in the figure.
sin(x/2)=|opp side|/ |hypotenuse| =
cos (x/2) = |adj side|/ |hypotenuse| =
from the famous identity: sin(2a)=2sin(a)cos(a), we have:
2sin(x/2)cos (x/2)=sin(x)
thus
(3a-1)(a-3)=0
thus a=1/3 or a=3
thus tan(x/2)=1/3 or tan(x/2)=3
Answer: {1/3, 3}
The answer to question 5 is -3.

<u><em>Answer:</em></u>
Elliot biked 70 miles
<u><em>Explanation:</em></u>
We are given that the total distance of the race is 100 miles
We are also given that Elliot covered 
of this distance
To get the number of miles covered by Elliot, we will simply multiply the ratio of the covered distance () by thetotal distance of the race (100 miles)
<u>This is done as follows:</u>
Distance covered = 
miles
<u>Therefore,</u> Elliot biked for 70 miles
Hope this helps :)
