after allowing 10% discount on the Marked price of an article is and then 15% vat is charge its price become Rs 16720 how much amount was given as discount

let marked prize=mp

discount=10%

sp=mp-d%ofmp=mp(1-10/100)=0.9mp

vat=15%

yep

step-by-step explanation:

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
