Count how many decimal places you need to move to the right until you get to:
1.203 and then multiply that by 10 raised to the power of the number of places you moved the decimal point...in this case it had to move 10 places so:
1.203X10^-10
You first simplify
tan(x) = cos(x)/sin(x) and cot(x) = sin(x)/cos(x)
Then you plug that in and then you simplify even more
Woman and men would be the same price, if the haircuts are very popular, each gender got the same haircut, then they also would be the same price, it is mostly about the prices, interestingness, and popularity or each barbershop, go by your nearest barbershop and see what prices they have. :))

an acute angle is any angle less than 90 degrees.
