Answer:
58
Step-by-step explanation:
For every triangle, all angles add up to 180. So you have to subtract 64 from 180 which gives you 116. You then take that number and divide it by two because there are two base angles, which gives you 58. The answer is 58.
The solution would be undefined, since it is not possible for 10 to be equal to -15. Hope this helps! :)
