The floor area of the model in the image below is 500 square inches, and the floor area of the house is 1,280 square feet. If the model has a room with a side length of 5 inches, then what is the scale factor for the model to the actual floor? A) 5 in:8 ft

B) 5 in:12 ft

C) 5 in:36 ft

D) 5 in:64 ft

Please help. I'm literally crying because I can't figure it out still.

B is twice of 55° (because it is an inscribed angle)

55 x 2 = 110

arcB = 110° is your answer

hope this helps
