Answer:
C
180(.6) because 40% off is 0.4 and what is left over is 60% or 0.6. When you multiply this you get 108. 5% sales tax is a 5% increase, so multiple 108(1.05) and you get $113.40.
The exact value of tan (π/6) is 1/√3.
Given a trigonometric function,
tan (π/6)
We have to find the exact value of the given function.
We know that, the value of π/6 in degrees is 30 degrees.
So here, we have to find the value of tangent function of 30 degrees.
We know that,
Tan (x) = sin (x) / cos (x)
Here x = π/6
Tan (π/6) = sin (π/6) / cos (π/6)
= (1/2) / (√3 / 2)
= 1/√3
Hence the tan (π/6) is 1/√3.
