There are no given coordinates, so it's impossible to answer your question. I'm sorry.
Answer:
100 degrees
Step-by-step explanation:
The angle x is opposite the angle that is 100 degrees.
Since they are opposite each other, they are vertical angles.
This means that they are congruent, or equal to each other.
Therefore,
x=100
x is 100 degrees
Multiply the tops and multiply the bottoms
Aka
5*21
-------
7*25
And simplify
