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
Answer:
b.
Step-by-step explanation:
its basically saying since x equals 10 and 10 is on both sides that if you add y to both sides itll still be equal hence, addition property of equality.
