Since there's no given exact measurement. I'll assume that the angle is by default 180 degrees.
If angle PQR measure 75 degrees.
then the measurement of angle SQR will be:
Angle PQR = 75
Angle SQR = 180 - 75 degrees
Angle SQR = 105 degrees
Part A: In order to make an equation without a solution, all you need to do is this:


This makes the equation impossible, as no number equals itself plus two.
Part B: This is easier. Literally every random equation should work.


Now, use substitution:

x = 2
Answer:
i know english only
Step-by-step explanation:
sorry but you stupit you not good at englis
Least common denominator is 36
54/x = 6...multiply both sides by x
54 = 6x...divide both sides by 6
54/6 = x
9 = x
