Answer:
249.6
Step-by-step explanation:
width x height x 1/2 = area fo a triangle
12(2) x 10.4(2) x 1/2 = 249.6
I assumed this means all of the surface area. Hope this helps. Sorry if I'm wrong.
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
