a and 35 degrees angles are vertical, so a =35 degrees,

angles a and b are in a straight triangle so a+b +90 = 180, so b = 180-90-35 = 55 degrees

angles c and 70 degrees are supplementary, which means c+70 = 180, so c = 180-70 = 110 degrees.

Answer: a = 35 degrees, b = 55 degrees, c = 110 degrees
