Answer:
75?
Explanation:
Isnt the total of the line suppose to equal 180*? if thats the case then the first angle 101* is 11 over the 90* mark meaning that you take 11 from the other side which would be 90-11 and that leave you with 79 but since the problem says +4 you would take 4 from 79 leaving you with 75. You would work backwards on the problem so the whole thing equals 180*
