how to do solve this some ​

Answer 1

Answer:

(a) 300 (b) 80 (c)60

Step-by-step explanation:

they are the angle of 360 degree

so answer (a) 360-60=300

(b) 360-70+50+160=360-280=80

(c)360-90+140+40+30=360-300=60

Answer 2

Answer: a=300 , b=80 ,c=60

Please mark it brainliest

Step-by-step explanation:

a=

sum of angles of circle is 360 degree

So,

x+60=360

x=360-60

x=300 degree

b=

x+70+50+160=360

x+280=360

x=360-280

x=80 degree

c=

x+140+90+40+30=360

x+300=360

x=360-300

x=60 degree
