Explanation:
For the first question the answer would be:
They would not be parallel, the reason why this is the case is because, in order for the window frame and glass to be parallel they would both need to have a 50 degree angle.
For the second question the answer is:
Yes, R and T are parallel and lines 3 and 8 are parallel too, so the theorem given is correct.
For the third question the answer is:
Angle 4 = 34 degrees. angle 4 is just a mirror of angle 2, so that would mean that angle 4 is 34 degrees.
And finally the last answer to the forth question is:
The value of X is: 17
Hope this helped!
