It would stay the same because 2 is lower than 5. Now if it would be 5 and up then it would change but in this case, 4 and lower stays the same. Hope this helps! :)
First lets solve for x we know 3x=90. In this case x=30. Now we can solve for y. We know the triangle needs to equal 180 so y+2(30)=180. So we get y=120. Hope it helps
