Answer:
I know that a= 124 but I'm afraid I don't know how to solve b. I thought I'd put down half an answer anyway incase that helps.
Step-by-step explanation:
The exterior circle angles all have to add up to 360 degrees so all you have to do is subtract 100 and 136 from 360 and you get 124 for a.
One times one plus two times one over ten plus four times one over one hundred plus three times one over one thousand
