Secants ⎯⎯⎯⎯⎯⎯⎯⎯⎯ and ⎯⎯⎯⎯⎯⎯⎯⎯⎯ intersect in the exterior of a circle. ∠ measures 27.42° and the measure of DE is 73.18°. Determine the measure of BC.
Answers
Answer:
BC = 18.34°
Step-by-step explanation:
Recall: Exterior angle formed by 2 secants = ½(the difference of the measures of the intercepts arcs)
Thus:
m<BAC = ½(DE - BC)
27.42° = ½(73.18 - BC) => Substitution
Multiply both sides by 2
2*27.42 = 73.18 - BC
54.84 = 73.18 - BC
BC = 73.18 - 54.84
BC = 18.34°

Answer:
P' = (2, -6)
Step-by-step explanation:
In this translation, you just need to substitute x and y into the given translation to find what P' is. (x is -6 since it's the x-value of P, and y is -2 since it's the y-value of P):
where T(x, y) = (x + 8, y - 4) and x = -6 and y = -2,
T(-6, -2) = ((-6) + 8), (-2) - 4) (substitute x and y into the translation)
T(-6, -2) = (2, -6) (add and subtract)
So, P' = (2, -6)

What will happen to a number, if it was added to its inverse?
Answers
Answer:
The word "inverse" in the question is ambiguous, since x usually has inverses under both addition and multiplication. ... If the question is asking about the additive inverse (opposite), then the sum is always 0 for any x . So the sum takes its maximum value for any x .
Step-by-step explanation:
Answer:
Zero
Step-by-step explananation:
An inverse is the opposite of another number, so if you add them together it would equal zero.
Here are a few examples.
5+-5=0
9+-9=0
150+-150=0
-220+220=0
-476+476=0
The inverse is simply the originall number, but on the opposite side of the number line. Meaning you add or take away the negative sign, depending on the original number.
Hope I explained well:)

Answers
Answer:
The answer would be : F.
Step-by-step explanation:
for this you should on look at the x axis line.
The left side is the negative side and the right side is the positive side.
As you can see the line from the circle on the negative side of the x axis is going to the positive side.
Meaning that X will be greater than -9
Thus we have this part of the answer so far
-9<x
(Before we proceed remember if the circle is not colored in that means it is either greater than or less then. So you would use these </>. But if it is colored in then it is either less than or equal to OR greater than or equal to. I don't have the symbols on my phone keyboard but they are just "<" or ">" with a line under them.)
The next point on the positive/right side is colored in and going towards the negative/left side therefore, X will be less than or equal to 2.
(2 being where the point is on the x axis line)
so we will get : -9 < x (less than or equal to sign) 2
