Question is on the picture Thanks in Advance

               •₁ same side interior angles  

               •₂ m∠1 = 78°,  m∠2 = 102°

               •₃ oars are parallel, conversed the same side interior angles theorem      

Step-by-step explanation:

•₁

The edge of the kayak is a transversal of lines created by oars. The angles are on the same side of transversal and between the oar-lines (inside the area between lines) so they are same side interior angles (or: consecutive interior angles)

•₂  

x = 10

m∠1 = 6x + 18 = 6•10 + 18 = 78

m∠2 = 9x + 12 = 9•10 + 12 = 102

•₃

The measures of angles 1 and 2 add to 180° (102+78=180) so they are suplementary angles. It means the oar-lines are parallel.

Based on:

Conversed the Same Side Interior Angles Theorem: If two lines are cut by a transversal and the same side interior angles are supplementary, then the lines are parallel.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
