9 will be the least number of boards to use because if you use anymore that it will be over 36 inches wide. 36 divide by 3.75 is 9.6
A because 1-10 would be -9 and she was a meter above so positive but they descended 10 meters no negitve
Answer:
a. 30 degrees
b. 60 degrees
c. 105 degrees
Step-by-step explanation:
Angle a is 30 degrees becuase it is congruent to the one right above it
Angle b is 60 degrees because the interior angles of a triangle always add up to 180. We know that angle a is 30 degrees and the angle with the mini square is a right angle, and right angles are always 90 degrees. Based on this information, we can subtract 90 from 180 followed by subtracting 30 from 90, which equals 60. Angle b is 60 degrees
Angle c is 105 degrees because a straight angle is 180 degrees. We know that one angle is 75, so we subtract 75 from 180 to get the difference. The difference is 105 degrees, which is also the measurement of angle c.
Hope this helps!
So, we write a fraction, which would be 12/100. Then we would do 12/100 = x/550. You could divide 100 by 550, which is 5.5. Then we would multiply 5.5 by 12, which is 66. So 66 people would be wearing glasses.
