-5 is the adjacent side, -12 is the opposite side, the hypotenuse is 13
Cos = adjacent/hypotenuse
Cos = -5/13

Answer:

$x = 34.8^\circ$

Step-by-step explanation:

Given

See attachment for triangle

Required

Find x

To do this, we simply apply sin formula which is:

$sin(\theta) = \frac{Opposite}{Hypotenuse}$

In this case, it is:

$sin(x) = \frac{8}{14}$

$sin(x) =0.5714$

Take arcsin of both sides

$x = sin^{-1}(0.5714)$

$x = 34.84791$

$x = 34.8^\circ$ --- approximated

Tip for rounding nearest 10th: if the 2nd number is above 5 it’s the one above, if it’s below 5 it’s the one below.
