Please help me with this. TWO LINES MEET AT A POINT THAT IS ALSO THE ENDPOINT OF TWO RAY'S. SET UP AND SOLVE THE APPROPRIATE EQUATIONS FOR m AND N.

Answer:
m=47, n=52
Step-by-step explanation:
m is equal to 90-43 since 43+m is a right angle (straight angle 180 is composed of two right angles). n is equal to 90-38. If you solve of the missing angle not given a variable, you find n as well because opposite angles are congruent and have the same measure.
