The circle below is a representation of a (huge) tire. 1. determine the circumference of the tire in terms of pi. 2. use the circumference to determine how many feet (to the nearest foot) the tire would travel if the tire performed 50 revolutions if the circumference is 1 revolution. radius is 3 ft.

In the following diagram it is given that dec, ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
