Find the cotangent of the real number

-

Step-by-step explanation:

Using the trigonometric identity

cot x =

Thus

tan( ) = - tan ()

Since is in the fourth quadrant where tan < 0

and

2π - = ← related acute angle

Then

- tan() = - , hence

cot () = = -

step-by-step explanation:

sry but any answer choices

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
