The GCF would be 14a, because 14a x 1 = 14a, and 14a x 2b = 28ab.
3/2 since you move 3 spaces horizontally (x) and 2 spaces up (y)
X+x+54=180
2x+54=180
2x=126
x=63
63+54=117
one angle is 63, the other is 117
That would be 0.9 because 9 is in the tenths place
If you have an angle and want to know its complement, you subtract it from 90 degrees. What angle, when subtracted from 90 degrees, gives the same value?
90 - x = x
The supplement of x is the angle that you add to x to make 180 degrees. In other words, 180 - x = the supplement of x.
