Use the unit circle to find the value of tan (-180º).

B. tan (-180°) = 0

Step-by-step explanation:

Tangent is the ratio of opposite to adjacent to an angle

From the unit circle; the opposite to our angle -180° is 0

The adjacent along the x-axis is 1

Therefore;

Tan (-180°) = 0/1

              = 0

Therefore; Tan (-180°) is 0

∠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.
