Answer:
86
Step-by-step explanation:
The average is the sum of all the grades divided by the number of tests.
83.8 = (84 + 79 + 82 + 88 + x) / 5
419 = 333 + x
x = 86
Based on the given figure above, we can find the measures of angle POS and angle POQ by analyzing it carefully. Look for POS and POQ where POS = 1/2 POQ. Base on this, we can conclude that <span>measure of angle POS = 60° and measure of angle POQ = 120°. Therefore, the answer would be option A. </span>
