answer:
B -2
Step-by-step explanation:
equation is x-6=5x+2 and you some it like you would for a regular linear expression
Answer:
Assuming that is a diameter.
Given that
And that point O is the center of the circle
Explanation:
Because angle AOB is subtended by arc AB from point O.
Arc AB is equal to the measure of that angle.
Since arc ABC is subtended by the diameter, the arc is 180°.
Answer:
100°
Step-by-step explanation:
the angles are vertical, so they are equal.
