During the rainy season the water level in a certain lake rises. A road already exists

through the school that goes over a circular lake. The local government wants to build

another road through the school that connects to this road but not go through the

lake. The city engineer can measure the road that already exists, and he finds that the

bridge portion of the road is 5 kilometers, and the portion of the road from the bridge to

where the new road will be is 4 km. How long the road will be constructed. ( Hint : Use

tangent line ).

**Solution: **

After using a babble translator with an ambiguity filter setting of 0.6

and applying novacula Occami: lex parsimoniae (Ocham's razor: law of parsimony)

I find that ...

...This is solvable by using the Secant-Tangent Product Theorem

(Total secant segment length)*(external secant segment length) = (length of tangent segment)^{2}

Bridge portion of the road (circle portion secant length) = 5 km

Road from the bridge to where the new road will be (external portion of secant length) = 4 km

Sum of above lengths (extended secant length) = 9 km

External portion times extended length = (4*9) =36 (Square of Tangent length)

Tangent length = sqrt(36)= 6 km (How long the road will be constructed)

idk Ginger.

It all looks good but I m not sure you used the right ambiguity setting.

If you miscalculated that then your whole answer is in dire jeopardy

I know what you mean ...

When I set the ambiguity filter to 0.5, the question changed to: **How do you thin out the population of an overcrowded school? **

**Solution: Put a road through the school. The slowest students and those who do not pay attention will be the first to go. **

(It’s easy to misapply Occam’s Razor)
