Answer:
100 degrees
Explanation:
i was looking for geography questions and stumbled upon this one. I am no math whiz but I am happy to help. This answer is not mine and I am sorry. It is by amritsinghpabla537 but m<ABG =10x so 10 times a number can’t be 98. m<ABC is an acute angle so it has to be less than 90. M<ABG needs to be higher than 90 cause it’s obtuse. So you’re left with 100.
