In the following figure, if l‖m, then find the measures of angles marked by a and b.
a = 90° and b = 90°
a = 55° and b = 125°
a = 70° and b = 110°
a = 60° and b = 120°
The pie chart shows number of boys in 8 schools. The total number of boys is 10,000. Number of boys in a particular school is shown as a % of total number of boys in all these 8 schools.
What is the ratio of total central angle formed by sector C, D and F to the total central angle formed by sector A, G and H?
