Answer:
x = -8
Step-by-step explanation:
To find x, we need to isolate it. So first, let's subtract 2.6 from both sides to get rid of it on the side with x:



Now, divide both sides by 3.2 (because notice how we are multiplying it right now - so we need to undo that, and so we do the inverse operation of division):

Notice how we are left with 1x on the left which is x, so we have successfully isolated x:

So, x = -8. Hope it makes sense, ask me any questions you may have! :)
Answer:
Step-by-step explanation:
(im presuming this is a triangle)
65 + 45 = 110°
angles in a triangle add up to 180°
180 - 110 = 70°
x = 70°
Since it has a line under > that means it equal to 7 and x is bigger than 7 so 8, 9, 10... so right
