Short answer: 60°
Explanation: All inner angle of a triangle add up to 180° so 180° - 60° - 60° = 60°
Subtracting the 2 already given angels must be subtracted from 180° to know the final angle

Hello!
You have to find what the rule is
12/24 = 0.5
6/12 = 0.5
-6/-12= 0.5
They multiply x by 0.5
the rule is multiply x by 0.5 or y = 0.5x
Hope this helps!
