Question

Please give me answer

Answer 1

Answer:

1. Angle at a point(360 degrees)= 360- 60 = 300

2. 70+50+160+x degrees= 360 degrees

   280+ x degrees= 360 degrees

    Collect like terms

x = 360-280 degrees=

x= 80 degrees

3. 30 + 40 + 90+ 140+ x degrees = 360 degrees

300+ x degrees= 360 degrees

x= 360-300

x= 60

Step-by-step explanation:

Answer 2

Answer:

a) 300°

b) 80°

c) 300°

Step-by-step explanation:

a) x=360-60=300°

b) x=360-(70+50+160)=360-280=80°

c) x=360-(30+40+140+90)=360-300=60°
