Trig equations to solve! A lighthouse is built on the edge of a cliff near the ocean, as shown in the accompanying diagram. From a boat
located 200 feet from the base of the cliff, the angle of elevation to the top of the cliff is 18º and the angle of
elevation to the top of the lighthouse is 28°. What is the height of the lighthouse, x, to the nearest foot?

∠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.
