55° and 125°
same side angles are supplementary
2 supplementary angles sum to 180°
let x be one angle then the other angle is x + 70 ( 70 greater ), hence
x + x + 70 = 180
2x + 70 = 180 ( subtract 70 from both sides )
2x = 110 ( divide both sides by 2 )
x = 55
the two angles are 55° and 55 + 70 = 125°
