Answer 1

Answer:

a in this we have find the sum of 3 angles =300 it is quadrilateral so all angle sum is to be 360 so unknown angle =360-300=60

b they are linear pair so the have same measurements 135 both

Answer 2

Answer:

a)  sum of any two adjacent angles = 180°

     Let unknown angle as x

70° + ∠x  = 180°

∠x = 180° - 70°

∠x = 110°

b) Let unknown angle as x

∠x = 135°   (vertically opposite angle)
