|-80|=80
|x| -≥ this symbol is named as mod
we use this to find the absolute value...
it can be explained easily as meaning like rounding off
I'm that even the number given inside in negative we should write the answer only in positive
negative number can never be the answer of absolute value
hope helpful

The identity in question is
cos(a - b) = cos(a) cos(b) + sin(a) sin(b)
so that
cos(a - b) = 12/37 cos(a) + 3/5 sin(b)
Since both a and b lie in the first quadrant, both cos(a) and sin(b) will be positive. Then it follows from the Pythagorean identity,
cos²(x) + sin²(x) = 1,
that
cos(a) = √(1 - sin²(a)) = 4/5
and
sin(b) = √(1 - cos²(b)) = 35/37
So,
cos(a - b) = 12/37 • 4/5 + 3/5 • 35/37 = 153/185
1. It depends on the form of "c". If we realize that a commission percentage of 10% is identical in value to 0.10, then we can compute the commission as 3600c. If the commission percentage of 7% is given as c=7, then we need to compute the commission as 3600·(c/100) = 36c. We will assume the former.
... (Bart's earnings) = 85 + 3600c
2. The cost of a rental is the base fee plus the mileage charge multiplied by the number of miles:
... (cost of renting) = 60.00 + 0.25m
