Yes, they are all actually B. Hope this helps!
Imagine that you kept drawing the circle around to include the entire angle. We know that the measure of that angle would be 360°, because there are 360° in a circle.
But instead, we stopped at 260°. We have x° left to get to 360°.
That's 360°-x°=260°.
x=100, so the answer is E
9x - 2x = 7x. 7x +3 is the answer. Hope it helps ;)
