Answer 1

A) x = 180-90-28 = 62°
y = 180-x = 180-62 = 118°

b) x = 180-100-35 = 45°
y = 180-35 = 145°

c) x = (180-70):2 = 110:2 = 55°
y = 180-55 = 125°

d) x = 180-90-40 = 50°
y = 180-x = 180-50 = 130°

e) y = 180-80 = 100°
z = 180-100-45 = 35°
x = 180-80-55 = 45°

Answer 2

A.x= 180-110=70
y=180-70=110
b. x=180-135=55
y=180-35=155
c.x=180-70/2=55
y=180-55=135
d. x=180-130=50
y=180-50=130

e . x= 180-135=55
y=180-80=100
z=180- 145=35

f.y= 180-120=60
