What’s the cot(180°) + (cos(180°)/sin(180°))
KatRina [158]

Answer:

the answer is 'undefined'

Step-by-step explanation:

Cot is defines as (cos x)/(sin x)

So we can rewrite our expression as...

(cos 180°)/(sin 180°) + (cos 180°)/(sin 180°)

or

2(cos 180°)/(sin 180°)

Cos 180° = 1, sin 180° = 0   (you get these from the unit circle)

so we have

2(1/0) = 2/0,  which is undefined, because we don't divide by zero

BDсStatementsReasons1. AB || CDAC || BD1. GivenIf two parallel lines are cut by a transversal, then:2. ZABC ZBCDLACB LDBC2.1-13.
Anna11 [10]

The diagram shows statements to prove that both triangles are congruent.

Hence;

\begin{gathered} (2) \\ \angle ABC\cong\angle BCD \\ \angle ACB\cong\angle DBC \\ Alternate\text{ interior angles are congruent } \end{gathered}\begin{gathered} (3) \\ BC\cong BC \\ \operatorname{Re}flexive\text{ property} \end{gathered}\begin{gathered} (4) \\ \Delta ACB\cong\Delta DBC \\ \text{Side}-\text{Angle}-\text{Side} \end{gathered}

Step 1 showed two sides that are congruent for both triangles

Step 2 showed two angles that are congruent

Step 3 showed two sides that are congruent

Therefore, the triangles are congruent by the side-angle-side theorem
