Answer:
m < 3 = 68°
Step-by-step explanation:
Given m<7 = 22°, apply the Alternate Interior Angles Theorem to solve for m<5 which is also 22°.
You can use the Vertical Angles Postulate to find the m<2 which is also 22°.
Given that m || n and y is perpendicular to m, making y also perpendicular to n.
Since x and y are parallel, x is also perpendicular to n.
This means m<2 + m<3 = 90°
22° + m<3 = 90°
m<3 = 68°
