Answer 1

Answer:

4) a) 70

B) 75

3)130degree(opposite angles are equal) or 60degree

Step-by-step explanation:

4) a) 3x + 20 = 0

you use formula

x + y = 180

x = 3x

y = 20

3x + 20  = 180

x+20=90

x=90-20

x=70

angleWZX  = 70degree

b) you use formula

x+y = 180

2x-15=180

x-15=180/2

x-15=90

x=90-15

x= 75

angleWZY = 75degree

3) use fomula

x+y=180

x = 130

120+y=180

y=180-120

y=60
