Tell whether the angles are supplementary or complementary then find the value of x.

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

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
