Answer:
5
Step-by-step explanation:
firstly, what are complementry angles.complementary angles are angles that su
m up to 90°
(12x-18)+(5x+23)=90
collecting like terms
12x+5x+23-18=90
17x-5-90=0
17x-95=0
17x=95
divide through by 17
x=5
To find the diagonal of the pool, you need to use The Pythagorean Theorem which is a^2 + b^2 = c^2. We need to find c, so we substitute in the sides, and it doesn't matter how we substitute because we are adding positive numbers so the answer will always be the same. So, 31.22^2 + 25^2 = c^2. After we calculate this out we get c^2. To find the diagonal or c, we square root c^2 to get a final answer of 39.9961 or 40 feet

Answer:
The equation of a circle:

Step-by-step explanation:
The equation of a circle:
(where the center is known as
and the radius, known as
).
-Since you already have the center and the radius, use them for the equation of a circle:
Center: 
Radius: 

After you have the equation of a circle, simplify the radius by the exponent
:

So, you have found the equation of a circle.
