What is the measure of arc AC? m< ABC = 78 degrees A.156 B.78 C.39 D.13

1 answer:

8 0

I don't see a figure, so I'll mention two possibilities. There are more possibilities. Since the arc is named arc AC, points A and C must be on the circle. Since I don't see the figure, I don;t know where point B is.

If point B is on the circle, then angle ABC is an inscribed angle. The measure of an inscribed angle is half the measure of the intercepted arc, so m<ABC = 156/2 = 78.

If point B is the center of the circle, then angle ABC is a central angle. The measure of a central angle is the same as the measure of the intercepted arc, so m<ABC = 156.

Do you have one of the two situations above?

There are infinitely How many pairs of numbers of which the sum of their cube roots is zero give two of these pairs

ivanzaharov [21]

Answer:

Infinite pairs of numbers

1 and -1

8 and -8

Step-by-step explanation:

Let x³ and y³ be any two real numbers. If the sum of their cube roots is zero, then the following must be true:

$\sqrt[3]{x^3}+ \sqrt[3]{y^3}=0\\ \sqrt[3]{x^3}=- \sqrt[3]{y^3}\\x=-y$

Therefore, any pair of numbers with same absolute value but different signs fit the description, which means that there are infinite pairs of possible numbers.

Examples: 1 and -1; 8 and -8; 27 and -27.
