Correct me if i am wrong pls.
Thx.
Minnie, you can find angle e by:
120 - 45 = __[ angle e ]___
for question two, it's 72 + 65 = ___ans___
the topic you are on is angles and the way that I used to solve this question is vertically opposite angles.

Can you explain why you use 120 degree minus 45 degree?
Can you also explain why you use 72 degree plus 65 degree?
So is Q1 answer 67.5 degree?
Q2 answer is 122.5 degree?
This are my own answers. Please correct me if I am wrong.
