Answer 1

Answer:

Step-by-step explanation:

i. b.96°

60°+y+x=180°                    (angles on a straight line)

60°+y+4y=180°                  (replaced x with 4y because VOA)

5y=180°-60°

5y=120°

y=24°

x=4y

x=96°

ii. d. 24°

iii. c. 42°

x+2z=180°

96°+2z=180°

2z=180°-96°

2z=84°

z=84°/2= 42°

iv. c.180°          (because they are one a straight line)

v. a. 2y+z=90°

4y+2z=180°

2y+z=90°
