Best ResponseYou've already chosen the best response.0That's a trick question. Every line has infinite length. Perhaps you mean the length of segment AB?

Best ResponseYou've already chosen the best response.0We can get these angles using the inverse tangent function. dw:1436220001584:dw

Best ResponseYou've already chosen the best response.0I don't think there is enough info on triangle ABP to answer unless we know that segment AB is parallel to segment L1L2. dw:1436220177111:dw

Best ResponseYou've already chosen the best response.0If segment AB and segment L1L2 are parallel, then you can find the length of segment AB.

Best ResponseYou've already chosen the best response.0Then we can use more angles. See below. dw:1436220516982:dw

Best ResponseYou've already chosen the best response.0No. The angles of the triangle are not that different in size, so one side can't that much smaller than the other side. \(x = \dfrac{4010~ft \cdot \sin 69^o}{\sin 61.9^o} \) Try again.

Best ResponseYou've already chosen the best response.0BTW, your calculation of the proportion was done correctly. You need to set your calculator to degrees. It is set to radians.
