Law of Cosines says

$b^2 = a^2 + c^2 - 2 ac \cos B$

$2 a c \cos B = a^2 + c^2 - b^2$

$\cos B = \dfrac{a^2 + c^2 - b^2}{2 a c}$

$\cos B = \dfrac{16^2 + 16^2 - 11^2}{2(16)(16)} = \dfrac{ 391}{512}$

$B = \arccos \dfrac{ 391}{512} \approx 40.2 ^\circ$

How do I write this fraction as a decimal 14 3/5

Softa [21]

we have

$14 \frac{3}{5}$

This is a mixed number

we know that

A mixed number is a combination of a whole number and a fraction.

$14 \frac{3}{5}$ is equal to

$14 +\frac{3}{5}$

where

$14$ is the whole number

$\frac{3}{5}$ is the fraction

$\frac{3}{5}=0.60$

$14 +\frac{3}{5} =14+0.60\\ \\ =14.60$

therefore

the answer is

$14.60$
