1a. For this one you need to use a protractor, and seeing how it's online, I'm guessing this question comes with a digital protractor. But, by the looks of it it's over 90degrees.

1b.Classifying TBE, to classify means to put in a group, in which the groups for angles are straight, acute, obtuse, and right.
Straight: is an angle of 180
Acute: Less than 90 degrees
Obtuse: More than 90, less than 180 degrees
Right: 90 degrees angle
Seeing as this angle is larger than 90, it will be obtuse.

The interior points, as in, in the angle, will be G and M.
The exterior points, as in, the outside of the angle, will be W and J.
