Given that line segment AD ll CL, AL is a transversal,
`angle DAL=angle ALC ` (alternate interior angles are congruent)`=33^o`
Now consider `Delta ALC, angle CAL=180^o-(33+53+40)=54^o`
Again consider `Delta AXC, angle AXC=180^o-(54+40)=86^o`
Opposite `angle DXL=angle AXC=86^o`
From `Delta LDC, angle LDC=180-(53+33+21)=73^o`
Finally, `from Delta ADC, angle ADC=180-(54+33+40)=53^o`
