Answer:
1. 37° 2. 140
Step-by-step explanation:
They are supplementary angles, so the angle measures equal a straight line, or 180 degrees. 180 - 143 = 37
Your answer is 84 because 8 of 12 is 94 and 4 of 3 is 12 so 94 minus 12 is 84
90*4 = 360
so all the scores need to = 360 for a 90 average
83+88+92 = 263
360-263 = 97
minimum score is a 97
