The measure of angle ADB is 23°
Since angle DAB is equal to angle 112.
angle ADC will be
180 - 112
= 68°
7x - 4 = 2x + 26
5x = 30
divide both sides by 5
x = 6
therefore, 7x - 4 = 7(6) - 4
= 38°
angle DEA =180 - 61
= 119
Therefore;
angle ADB = 180 - (119 + 38)
= 180 - 157
= 23°
Therefore, the measure of angle ADB is 23°
