Answer:

10. 105

11. 75

12. 75

13. 105

14. 75

15. 105

Step-by-step explanation:

Notice that 75? Anything that is adjacent (has a common vertex like 75º) to the vertex is a linear pair. here is an example below:

Since there is only THAT 75, you must find the supplementary angle (adds up to 180). and remember in order to get a supplementary angle it has to be a STRAIGHT LINE and HAS TO EQUAL 180. (4, 1 in your image)

180 - 75 = 105.

and also it's also a linear pair so it reflects too which makes things a lot easier!

So, if 4 is 75 and it reflects, then that means 2 is also 75. 1 is 105 and it reflects so 3 has to be 105. and the same for the rest of the numbers.

Hope this makes sense
