18. The outline of a sign for an ice-cream store is made by placing of the circumference of a circle with radius 2 feet on top of an isosceles triangle with height 5 feet, as shown above. What is the perimeter, in feet, of the sign?
I want you to find the angle measure of the bottom two angles and the top angle. The isosceles triangle splits up into two 30:60:90 right triangles. But how does ETS maintain the 30:60:90 ratio?
It looks exactly like the description; the file is too big, rats.
I am pretty sure curly's question is incomplete. I think this is the complete version:
the outline of a sign for an ice-cream store is made by placing 3/4th of the circumference of a circle with a radius 2 feet on top of an isoceles triangle with height 5ft..what is the perimeter ,in feet , of the sign?
