Answer:
Supplementary
x=34
Step-by-step explanation:
The 2 angles are on a straight line. Therefore, they are supplementary. This means, that if the angles are added together, they must equal 180 degrees.
Therefore,
x+4x+10=180
Now, we have an equation, and can solve for x. To solve for x, we have to get x by itself.
First, combine like terms. Add the terms with a variable together.
(x+4x)+10=180
5x+10=180
Next, subtract 10 from both sides, because 10 is being added onto 5x.
5x+10=180-10
5x=180-10
5x=170
Now, divide both sides by 5, since 5 and x are being multiplied.
5x/5=170/5
x=170/5
x=34
So, the angles are supplementary and x=34
