Similar example: if 1 inch = 50 miles then 3 inches on a map would mean... 1 inch/50 miles = 3 inches/x miles or just 1/50 = 3/x

so you can use that to find the actual distance x that 3 inches represents on a map

we want arc RF, so we need to find central angle FDR

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.2
to find the central angle, you use the inscribed angle theorem

is equal to 2 times any inscribed angle which cuts off the same arc
