What is the measure of q to the nearest whole degree?

Step-by-step explanation:

In the given figure , we have a triangle having sides , 18 , 17 and 20.

Law of cosines  :-

, where a, b and c are the sides of the triangle and A is the angle opposite to side a.

Since angle Q is opposite to side MN with measure 17 .

Put a= 17 , b=18 and c=20 in the equation , we get

4

step-by-step explanation:

noncoplanar points are points that do not lie on the same line.
