A swimmer dives 10 feet below the surface of a lake

Answer:
She must swim 10 feet before she reaches the surface; from <em>level -10</em> to<em> level 0 (Equation: </em>)
Step-by-step explanation:
Based on the information provided, you can assume that the surface of the lake is at <em>level 0.</em>
You know that the swimmer dives 10 feet below the surface; this is the <em>level -10 .</em>
This means that she must swim 10 feet from the <em>level -10</em> to the level 0 in order to reach the surface of the lake.
Therefore, to find how far she must swim before she reaches the surface, it is necessary to add<em> levels -10 </em>and <em>+10</em> to get the<em> level 0.</em> This can be represented with the following equation:

Answer: P = 166 units
Step-by-step explanation: Each point on the triangle has lines that are tangent to the circle in the triangle, meaning that those lines form a 90° angle to the middle point in the circle. There is also a rule that states if there are tangent lines coming from the points and if the points have at least one given side length, the other side will have the same side length. So if one side on point D is 41, then the other side connected to the point is 41. I added up all of the side lengths; 41 + 41 + 30 + 30 + 12 +12 = 166 units.
I hope this helps!
