Answer 1

56 )  

a)   x = 85°  y  = 30°

y = 180 -  (180 - 105 * 2 )  

y =  30°

x = 180 - 10 / 2

x = 85

___________________________

b)   x = 40°   y = 20°

x = 180 - 100 / 2

x = 40

y = 60 - 40

y = 20

____________________________

c) x = 10° y = 70°

x = 180 -  80 * 2

x = 10°

y = 80 - 10

y = 70

______________________________

d) x = 90°  y = 30°

4y = 180 - 60 = 120

y = 30

x = 180 - 60 + 30

x = 90
