Answer:
60°
Step-by-step explanation:
tan 60 = sin 60 / cos 60
= [(root 3) / 2] ÷ [1/2]
= root 3
[sin 60 = (root 3) / 2 ; cos 60 = 1 / 2 ]
Clever !
The two square roots of 50 will do that.
They are irrational numbers, so I can't write down their exact values.
They are approximately +7.0711 and -7.0711 (rounded) .
Answer:
13! or 6227020800
Step-by-step explanation:
With no restrictions, we can figure out the answer to be 13! by the following analysis:
For the first position in line, there are 13 different students who could fill that spot. If we fill it and proceed to the next position in line, there are now only 12 students left who can fill it, since one is already in line. Then the next position only has 11 possibilities, and the next 10, and so on.
Multiplying all of this together gives us 13*12*11*10*9*8*7*6*5*4*3*2*1 or 13!
