Answer:
x=60°
y=37°
Step-by-step explanation:
In ∆ADC,
angle DAC + angle ADC + angle ACD = 180°
Hence,
50°+70°+x°=180°
120+x=180
hence,
x=60°
angle ADB + angle ADC=180°
Let angle ADB = z
therefore,
z°+60°=180°
z=120°
In ∆ABD,
angle BAD + angle ABC+ angle ADB = 180°
23°+120°+y°=180°
143+y=180
hence,
y=37°
