The measure of the central angle of the sector representing number of seats of party F is ________ degrees.

Solution

Number of seats of party F = 90

Total number of seats = 100 + 15 + 25 + 40 + 60 + 90 + 70 = 400

=> Central angle of the sector representing number of seats of party F

= $$\frac{90}{400}\times360^\circ$$

= $$\frac{90\times9}{10}=81^\circ$$
