The value of 1 raised to any exponent would be 1 because no matter how many times you multiply 1 and 1, it will still be one. So 1 to the power of 200 would be one because you are multiplying 1 two-hundred times.
Final Answer: The answer would be one
Answer:
A
Step-by-step explanation:
The Tangent-Secant Exterior Angle Measure Theorem states that if a tangent and a secant or two tangents/secants intersect outside of a circle, then the measure of the angle formed by them is half of the difference of the measures of its intercepted arcs. Basically, what that means here is that
equals half of the difference of
and the measure of the unlabeled arc.
First, we need to find the measure of the unlabeled arc, since we can't find
without it. We know that the measure of the full arc formed by the circle is
, so the measure of the unlabeled arc must be
by the Arc Addition Postulate.
Now, we can find
. Using all of the information known, we can solve for
like this:

Hope this helps!
You could round 77 to 80 and 65 to 70 and then add 70 and 80 and you will get 150
