Question

HELP ME PLEASEEE!!!!!!! I am stuck

Answer 1

Answer:

X = 62

Step-by-step explanation:

The inside of a triangle is always equal to 180º therefore, you need to add everything up to equal 180. It should look like

(x + 1) + 55 + x = 180

Now you just solve.

Since there are 2 x's you can combine the like terms making them equal 2x

Now the equation should look like 2x + 1 + 55 = 180

Simplify the other like terms: 2x + 56 = 180

Now you want to get x by itself so you subtract 56 from both sides:

2x + 56 = 180

    -56      -56

------------------------

2x = 124

Now to finish getting x by itself, divide both sides by 2.

2x = 124

-----   ------

2         2

x = 62

FINALLY you plug in x to see if it worked.

(62 + 1) + 55 + 62 = 180
