3x+5 + 2x+10 = 180
5x + 15 = 180
5x = 165
x = 165/5 = 33
angle ABD = angle CBE
angle CBE = 2x + 10 = 2(33) + 10 = 66+10 = 76
angle ABD = 76
angle DBE = angle ABC
angle ABC = 3x + 5 = 3(33)+5 = 99+5 = 104
angle DBE = 104
to confirm i didn't mess up
the sum of angles should be equal to 360
104*2 + 76*2 = 208 + 152 = 360
