AED and ABC are straight lines
EB is parallel to DC
Angle EBC = 148
Angle ADC = 63
Work out the size of angle EAB
Angle C and B are same side interior angles that sum up to 180.
So angle C is 32 (180-48)
ADC is a triangle that also sums up to 180.
So angle A + D + C = 180.
We know angle D and C.
So angle A + 63 + 32 = 180.
Angle A = 85. :)))
