$\cos (B) = \frac{10}{16}$

Step 1

Subtract $\frac{10}{16}$ from both sides of the equation.

$\cos (B) - \frac{10}{16} = 0$

Step 2

Cancel the common factor of $10$ and $16$ .

Step 2.1

Factor $2$ out of $10$ .

$\cos (B) - \frac{2 (5)}{16} = 0$

Step 2.2

Cancel the common factors.

Step 2.2.1

Factor $2$ out of $16$ .

$\cos (B) - \frac{2 \cdot 5}{2 \cdot 8} = 0$

Step 2.2.2

Cancel the common factor.

$\cos (B) - \frac{2 \cdot 5}{2 \cdot 8} = 0$

Step 2.2.3

Rewrite the expression.

$\cos (B) - \frac{5}{8} = 0$

Step 3

The degree cannot be determined because $\cos (B) - \frac{5}{8}$ is not a polynomial.

Not a polynomial
