Question

what is tan 180 degree ​

Answer 1

Answer:

The resistance-change factor per degree Celsius of temperature change is called the temperature coefficient of resistance. This factor is represented by the Greek lower-case letter “alpha” (α). A positive coefficient for a material means that its resistance increases with an increase in temperature.

Answer 2

Answer:

The answer is 0

Step-by-step explanation:

tanA = sinA ÷ cos A

= sin 180÷ cos 180

= 0/-1

= 0
