Answer:

I think it's -7x? not sure though

Step-by-step explanation:

(x-9)(x+2)=x^2______-18

x^2+2x-9x-18=x^2____-18

x^2-7x-18=x^2____-18

That's what I got don't quote me on it though. Sorry if I couldn't help much

Hey there! :)

Answer:

x = 65°

Step-by-step explanation:

Find the measure of the other two angles using the Supplementary Angles theorem:

180 - 105 = 75°

180 - 140 = 40°

The sum of all of the angles in a triangle is equal to 180°, therefore:

180 = 75 + 40 + x

180 = 115 + x

65 = x

x = 65°
