Answer: Is this a legitimate question?
Step-by-step explanation:
This is a pretty bad question but I think the answer they're looking for is
angle
circle
line segment
We define arcs in terms of circles and parallel lines in terms of lines (though not necessarily line segments, so this is a bit of a judgement call).
1. First of all, this is a isosceles triangle, meaning measurement I=58°, which makes it way easier to find T.



1. m{t}°=64 m{I}°=58
2. This one is easy because algebra is the key.

Add like-terms.



x=5
The only thing that confuses me is the y. Is it 7xy, y as a side, or what? Feel free to reply
