Answer:

x=45

Explanation:

In a triangle, all of the interior angles add up to 180 degrees. Knowing this, we can construct the following equation and solve for x:

$x+2x+45=180\\3x+45=180$

Subtract both sides by 45

$3x+45-45=180-45\\3x=135$

Divide both sides by 3

$(3x)/(3) =(135)/(3) \\x=45$

I hope this helps!
