Well...it says the sum of the angles measure 360...so lets set them equal to 360
40 + x - 10 + 1/3x + x - 20 = 360...combine like terms
2 1/3x + 10 = 360
7/3x = 360 - 10
7/3x = 350
x = 350/(7/3)
x = 350 * 3/7
x = 1050/7
x = 150 <=====
Company A offer
2,432×24(semimonthly)
=58,368 per year
Company B offer
2,390×26 (biweekly)
=62,140 per year
So company B pays a greater annual salary
Hope it helps!
