Question

I need this answered correctly and fast! Please help me I beg of you.

Answer 1

Angle c equals angle a because they are vertical angles

Answer 2

You have no number values there; the best I can do is tell you that c = 360-a-b-d.  Since b and d are the same measure, we can rename d as b, so your equation is c=360-a-2b.  But since a and c are the same, rename a as c to get an equation of c=360-c-2b.  Now add c to both sides to give you 2c=360-2b and c=180-b.  Can't do anything else with no values.
