Answer:
173
Step-by-step explanation:
BCE: 79+73=152
180-152=28
EDC: 37+96=133
180-133=47
112+28= 140+47= 187
360-187=173
for triangle EBC:
angleEBC+angleBCE+angleCEB=180
73+79+angleBEC=180
AngleBEC=28
for traingle EDC:
ECD+EDC+CED=180
96+37+CED=180
angleCED=47
for angleAED:
AEB+BEC+CED+AED=360
112+28+47+AED=360
AED=360-187
AED=173
