The cost of production of an article is made up as follows: Labour N70, Power N15, Materials N30, Miscellaneous N5. Find the angle of the sector representing Labour in a pie chart
210o
105o
105o
175o
90o
Forklaring
Total cost of production = N120.00
Labour Cost = \(\frac{70}{120}\) x \(\frac{360^o}{1}\)
= 210o
Labour Cost = \(\frac{70}{120}\) x \(\frac{360^o}{1}\)
= 210o
