Step-by-step explanation:
These two angles are supplementary. <em>This means their angle measurements add up to 180°</em>.
We know the measure of both angles, so we can add up the measurements and make them equal to 180.
We can now solve for x.
So .

You can use the proportion <u />
or
=
, where you fill in what you know, crossmulitply, and solve for x. You can also write it as an equation, where of=mulitply and is=equal to, and the percent is expressed as a decimal. Your two different equations would be .34x120=x and
=
Answer:
x=30
Step-by-step explanation:
Since the measure of an exterior angle is equal to the sum of any two angles in a triangle, the equation would be 4x-18=2x+6+36. Solve this, and we get x=30.
