X - The total cost
3 persons
Below $120 p/p
Then
120 * 3 = 360
X < 360/3
You have to start with thy x and the division than the minus and the plus
So for the 40-40-90 degree triangle, whenever the two legs are x values, then the hypotenuse is x value times the square root of 2.
--> a changed into a√2
√2 changed in √2 * √2
= 2
So the hypotenuse of the 40-40-90 degree triangle is 2.
Now for the 30-60-90 degree triangle, the smallest leg with the value of x is then changed to the value of x√3 if finding the longer leg.
-> a is changed to a√3
2 is changed into 2√3
So, y is 2√3 or approximately 3.46 units.
Multiply the amount of inches it is by 30 and you will know what the size is in feet.
