Answer:

60°

Step-by-step explanation:

Here we are given that the number of convertibles cars. Total number of cars owned by the dealers is 90. We have to draw the pie graph for above ratio. The pie chart is a circular statistical graph , where the different portion in form of sectors on the circle showing the amount of different entities.

The angle covered by an entity is in the same proportion as its number is in ration to the total number of all the entities.

Hence

$\frac{15}{90}=\frac{\theta}{360}\\\\\theta=\frac{15*360}{90}\\\theta=\frac{15*4}{1}\\\theta=60\\$
