What is the length of side Ef? Round
your answer to the
nearest tenth.

11.1

Step-by-step explanation:

Here, we want to get EF

To do this, we use the appropriate trigonometric ratio

we have the side facing the right angle as the hypotenuse

the measure of this is 18

The side facing the angle 38 is EF

This is the opposite to angle 38

The ratio of the opposite to the hypotenuse is equal the sine

sin 38 = EF/18

EF = 18 sin 38

EF = 11.1

∠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.

i think that you should ask google for the answer to that problem because if we don't know it google does
