Ahelicopter leaves an airport and flies south at 180 mi/h. thirty minutes later, an airplane
leaves the airport and follows the same route as the helicopter, only at a higher elevation. the
airplane is flying 330mi/h. how many minutes will it take for the airplane to catch up with
the helicopter? (hint: 30 minutes is hour.)

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

11

step-by-step explanation:
