Question

Determine x, y , e z :

Answer 1

11) a)90 + x + 20 = 180
110 + x = 180
x = 180 - 110
x = 70

y + 140 = 180
y = 180 - 140
y = 40

90 + 40 + 20 + z = 180
150 + z = 180
z = 180 - 150
z = 30

b)135 + â = 180
â = 180 - 135
â = 45
60 + 45 + x = 180
105 + x = 180
x = 180 - 105
x = 75

75 + y + 45 = 180
120 + y = 180
y = 180 - 120
y = 60
