The measure of angle t = 71 degrees. The measure of angle d=49 degrees. The sum of angles in any triangle is 180 degrees. The measure of each angle in an equilateral triangle is 60 degrees. I believe that z=100 degrees. X=40 degrees. A circular window and a rectangular window are NOT congruent. I believe they other sides are both 15cm each. The measure of angle a is approximately equal to the measure of angle e. Then CD=GH. Please Brainliest.
