Solve for c of the right triangle

Ede4ka [16]

In order to solve this triangle we must use cosine law:
$c^{2} = a^{2} + b^{2} - 2ab*cosC$

Now let's plug in the values we are given:
$c^{2} = 5^{2} + 8^{2} - 2(5)(8) * cos 67$
$c^{2} = 25 + 64 - 80*cos67$
$c = \sqrt{80-cos67}$

How do I find the quotient 2/5 divide by 1/4

Artemon [7]

Answer:

A. $\frac{2}{5} \times 4$

Step-by-step explanation:

This, we would have:

$\frac{2}{5} \times 4$

$= \frac{8}{5}$
