Why was my question deleted..
here it is.. again.

How many sides does a regular polygon have if each exterior angle measures 72a.3b.4c.5d.6

1) in triangle the, what is the measure of angle t (in degrees)? 2) in triangle bat, the measure of angle b is 66∘, and the measure of angle t is 77∘.what is the measure of the exterior angle at a (in degrees)?

Can you me find the slope! (30 points)
