Answer:

Equation 5x+15=180°

x=33°

Explanation:

Angles on a straight line always add up to 180°.

Form an equation:

4x+15+x=180° (Both of the red and blue angles add up to make the straight line).

Collect like terms:

Like terms are terms with the same variables and powers.

4x+x=5x

Put it back into an equation:

5x+15=180°

To find x, you would have to do inverse operations to isolate it.

180-15=165°

5x=165°

165÷5=33° (We divide by 5 because, in algebra, when a number is next to a letter it means times and as we want the inverse we divide).

So, x=33°

Hope this helps :)
