Answer:
B) 480
Step-by-step explanation:
The given is a regular hexagon so all interior angles are equal to each other their to find the sum:
4*180 = 720 to find the sum of <p+<q+<r+<s we divide this result by 6 because the hexagon has 6 interior angles, then multiply the result by 4
720/6 = 120
<p+<q+<r+<s = 120*4
<p+<q+<r+<s = 480
