Question

I need the help please

Answer 1

The answer is 45

2x+45+x=180
3x+45=180
3x=135
X=45

Answer 2

x = 45

Step-by-step explanation:

We know that adding these angles together will result in the whole line, which means together they are supplementary. We know that a straight line is equal to 180, so we will simply add these two together and set them equal to 180.

$2x+45+x=180$

Add like terms.

$3x+45=180$

Subtract 45 from both sides.

$3x=135$

Divide.

x = 45
