--- inverse
Required

For two functions f(x) and g(x) where f(x) and g(x)are inverse;

So, by comparison:

Answer:
Step-by-step
sum of the adjacent angles of parallelogram is supplementary.
Therefore,
Q + R = 180°
4y+7 + 10y-37 = 180°
14y - 30° = 180°
14y = 210°
y = 210°/14
y = 15°
Could not found X in the question.
Answer:
