Para encontrar el valor de las razones trigonométricas de los ángulos de 30 y 60, zamos un triangulo equilátero cuyo lado mide dos unidades. Ahora, emplea un triangu.
equilatero como el mostrado en la figura para hallar el valor de las funciones trigonome
tricas de los mismos ángulos. Con esto favoreces la competencia genérica 41​

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

∠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.
