If the measure of abc = 180o, and the length of ad and dc are equal, which is the measure of acd?

if the angle abc will be equal to 180 degrees then we know that abc is a straight line. 

if ad and cd are equal,you can now make  an isosceles triangle. 

the angles of that triangle be contingent upon the length of ad and cd but dac and dca are identical.

so in equation, it will look like: acd = ac + cd = 180 + 90 =   290°

answer is 67%
