The Law of Cosines can be used.

If the given angle is opposite one of the given sides, the Law of Sines can be used.

Law of Cosines:
.. c^2 = a^2 +b^2 -2ab*cos(C) . . . . . for any permutation of sides a, b, c, and opposite angle C

Law of Sines:

Drag the choices into the boxes to explain how all real numbers have a decimal expansion. The decimal forms of some real numbers

zvonat [6]

Answer:

$\frac{3}{16}$

$4\frac{2}{11}$

$\sqrt{5}$

Step-by-step explanation:

$\sqrt{5}=2.2360679...\\\\\frac{3}{16}=0.1875\\\\4\frac{2}{11}= \frac{46}{11}=4.18181818...$

The decimal forms of some real numbers, like $\frac{3}{16}$ , terminate, while the decimal forms of other real numbers, like $4\frac{2}{11}$ , do not terminate, but have a repeating pattern. Still other real numbers, like $\sqrt{5}$ , have decimal forms that neither terminate nor repeat.
