The sum of the two angles is 180°. Their difference is 70°. Find the angles.
Let larger be L, and smaller, S

We then get: L + S = 180 -------- eq (i)

L - S = 70 ------ eq (ii)

2L = 250 ------- Adding esq (i) & (ii)

L, or larger angle = highlight_green%28matrix%281%2C3%2C+250%2F2%2C+%22=%22%2C+125%5Eo%29%29

Smaller angle: highlight_green%28matrix%281%2C3%2C+180+-+125%2C+%22=%22%2C+55%5Eo%29%29
