A 180 degree angle is formed by two adjacent angles. One angle has a measure of ( 2x+3) and the other has a measure of (x-6). What are the measures of the two angles that make up the straight line?
186 and 88
125 and 55
121 and 59
129 and 51
121 and 59
(2x+3) + (x-6) = 180
3x - 3 = 180
3x = 183
x = 61
Therefore, the two angles are:
2(61) + 3 = 125
61 - 6 = 55
So, the angles are 125 and 55.
