On a right triangle, to find one missing side you can use this equation
a^2 + b^2 = c^2
a and b are the sides next to the right angle, and c is the hypotenuse (side not connected to right angle).
You first need to find the length of the dotted line before finding x. This is because to be able to use the above formula, you have to know the length of two out of three of the sides.
To solve the length of the dotted line, note that it also makes a triangle with the 5 unit line and the 5 √5 unit line. You can plug these numbers into the formula.
(5)^2+b^2=(5 √5)^2
25+b^2=125
b^2=100
b=10
Now that you know the length of the dotted line is 10 units, you can now solve for x
(20)^2+(10)^2=x^2
400+100=x^2
500=x^2
x= √500, which equals 22.361

Step-by-step explanation:
start at y intercept +5. Go up 3 points then go to the right 8 points and keep on doing that. Formula for slope rise/run. Rise is 3. Run is 8. Then connect the line.
Using the concept of number line, the solution to the questions posed are :
- <em>Pool</em><em> </em><em>surface</em><em> </em>
- <em>The</em><em> </em><em>height</em><em> </em><em>of</em><em> </em><em>slide</em><em> </em><em>is</em><em> </em><em>12</em><em> </em><em>meters</em><em> </em><em>above</em><em> </em><em>the</em><em> </em><em>pool</em><em> </em><em>surface</em><em> </em>
- <em>The</em><em> </em><em>level</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>bottom</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>pole</em><em> </em><em>should</em><em> </em><em>be</em><em> </em><em>marked</em><em> </em><em>as</em><em> </em><em>-</em><em>3</em>
The pool surface would be treated as sea level surface, such that, position below are marked as negative and position above are marked as positive.
- Therefore, the surface of the pool is <em>marked</em><em> </em>as the sea level position, 0.
- Since the slide is above the surface of the pool, it's value will the positive. Hence, the height of the slide is 12 feets.
- The marked position is below the <em>pool</em><em> </em><em>surface</em><em>,</em><em> </em>hence, it will take up a negative value of - 3 feets.

Answer:
The exponent is 5 because a exponent is what the number times itself like 3^2 is 9.
