24^2= 20^2+34^2-2(20)(34)cos(q)
576=400+1156-(1360)cos(q)
576=1556-(1360)cos(q)
-980= -(1360)cos(q)
to the nearest whole degree, the measure of angle q is degrees.

50 degrees.

Step-by-step explanation:

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

- Knowing that:

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

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

To the nearest whole degree, this is:
