In geometry, you will learn that supplementary angles add up to 180 degrees. therefore, if two angles have exterior rays that lie on a line, those two angles are supplementary and they add up to 180 degrees. supplementary angles are shown below:
you can use this information to set up an equation to solve the problem below for x.
angle 1 has measure "x". angle 2 has measure "2x + 30". find x.
hint: use the fact that these two angles lie on a line and are therefore supplementary to write the equation:
x + 2x + 30 = 180
then solve for x.
