do you know what an isosceles triangle is and what its properties are?
anonymous
  • anonymous
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 fill-in 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 = (180-x)/2?

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