Answer: 50 degrees.

Step-by-step explanation:

To find the measure of the angle Q, you need to follow these steps:

- Knowing that:

$-980= -(1,360)cos(Q)$

You can divide both sides of the equation by -1,360:

$\frac{-980}{-1,360}=\frac{-1,360cos(Q)}{-1,360}\\\\\frac{49}{68}=cos(Q)$

- Finally, using the inverse function of the cosine, Arccosine, we get:

$Q=Arcos(\frac{49}{68})\\\\Q=49.89\°$

To the nearest whole degree, this is:

$Q=50\°$
