Question

I need help findind m angle 12 =?

m angle 9 = 80° and m angle 5= 68°​

Answer 1

12 should equal 100°

Answer 2

I think the answer is 12 = 100

Explanation:

since 9 = 80 and that is the same for 11, if you do 180 - 80 = 100 which would be the answer for 10 and 12. Thus 12 = 100 based on the info given.

Hope this helps :)
