WILL GIVE BRAINLIEST! Which equation could be used to find the value of x?

Picture: Triangle DEF where angle E is a right angle. DE measures 55. EF measures x. Angle D measures 49 degrees.

A) cos 49° = x over 55
B) tan 49° = x over 55
C) cos 49° = 55 over x
D) tan 49° = 55 over x.

answer:

B or d but i say d

Step-by-step explanation:

mark if it right i hope it help

∠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.
