55 + x = 180
x = 180 - 55
x = 125
180
t + 98 + 55 = 180 t + 153 = 180 t = 180 - 153 t = 27
100+80, 99+81, 98+82....
125 + 55 = 180
To solve this one, subtract 50 from 180 and you'll have your answer.
110
It is: 126 plus 54 = 180
a + 3a + 5a = 180 9a =180 a = 20
It is: 97+83 = 180
It is: 157+23 = 180
It is 90+90 = 180
It is 134+46 = 180
