Two parallel lines are cut by a transversal

Question

Suppose
m∠438°
Find
m∠6 and m∠7

* m∠6 and m∠7 are corresponding angles *

Answer 1

You say

Suppose m∠438°

what does that mean?

Hmm. Maybe you mean

m∠4 = 38°

Not sure what the figure looks like, but corresponding angles are congruent. Check for adjacent angles or alternate/vertical angles.

It's kind of hard to answer a question about a diagram when so little information is provided...
