Which function's graph has a period of 2? A. y = 3 cos pix
B. y = - 4 sin 2x
C. y = cos (x - pi/2)
D. y = 2 sin 3x

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

yes

step-by-step explanation:

give me the question

\

∠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.

5/12, or 5: 12
