Yeah. I figured angles B and DAB must be equal, angles CDA and CAD must be equal, and angles B and C must be equal

you are almost there  now assign a symbol to angle ABD  lets call it x, and fillin all the other angles you know using this symbol, e.g. from what you have already said we get: dw:1351641960334:dw now find y in terms of x and then use the property of the sum of the angles in a triangle to solve for x.

HINT: Use the angle sum of a triangle in triangle CAD to express y in terms of x.

Using triangle CAD, y = (180x)/2?

I plugged that in for y: 180=3x+[(180x)/2] And found x=36
