Two ways:
Step-by-step explanation:
1. First way. Using the trig unit circle.
tan (pi - x) = - tan x
2. Second way. Apply the identity:
tan(a-b)=tan a- tan b/ 1 - tan a×tan b
tan (π - x)= tan π - tanx/1 - tan(π)×tanx
Since tan (pi) = 0, therefor:
tan(π−x)=−tanx
If you want to know the answer you need to give us the question.
Answer:
C is the answer
Step-by-step explanation:
Answer:
volume of a cylinder is πr^2h
hence 22÷7×5×5×8 gives 628.57
