line segment? please be more specific, are there any answer choices?
Discount %= 10%
Discount= x × 10%= x/10
Price after discount =x-(x/10)= 9x/10
But, given price after discount = rs 450
9x/10=450
9x=4500
x=4500/9= rs 500

Csc (pi/2) or the cosecant of (pi/2) can be obtained by using a calculator.
In terms of degrees, pi/2 is equivalent to 90 degrees. Cosecant is also the reciprocal of sine. Since sin 90 is equal to 1, obtaining the reciprocal of 1 should yield csc (pi/2). Since the reciprocal is simply equal to 1, then:
