Question

Please help me finding both angles, thanks :)

Answer 1

Both are 123

When dealing with angles you have to remember that all angles add up to 180, “the line angle” as I like to call it, it’s because 180 is completely flat.

2: Here you can use your eyes to see the angle is wider than 90, ”a perfect right”. So you can easily assume that the angle is gonna be 123.

1: the angle here shares the same place as your original angle. So you can easily assume that they have the same degree

Simple things very clear, hope this helps
