Answer:
118° 
Step-by-step explanation:
When two parallel lines are cut by a tranversal, then the exterior angles are supplimentary and the corresponding angles are congruent. 
Therefore the angle above (15x - 17)° is also (5x + 17)° and the angle below (5x + 17)° is also (15x - 17)°. 
Angles on a straight line adds up to 180°. So to know the measure of the larger angle we must both equations and equal it to 180° to find x in order to know the larger angle.
(5x + 17) + (15x - 17) = 180
5x + 15x + 17 - 17 = 180
20x = 180
20x/20 = 180/20
x = 9° 
Nkw let's substitute x = 9 into the equations 
5x + 17 = 
5(9) + 17 = 
= 62° 
15x - 17 =
15(9) - 17 =
= 118° 
Both equations should add up to be 180°. 
Therefore the measure of the largest angle is 118°.
