Answer:
b=74 degrees c=1O6 degrees
Step-by-step explanation:
B is 74 because its across from the 74 degrees
C is 1O6 degrees because 18Odegrees-74degrees-1O6degress
15. 70° because a right angle is 90° and we have the angle of ADB which is 20°. So 90°-20°=70°.
16. 70° because angle PSQ is 60° and angle QSR is 10°. So 60°+10°=70°.
17. 55° because it says it in the explanation. I assume this is a typo and they meant to ask the measurement of ADC and in that case it would be 130° because angle ADB is 75° and angle BDC is 55°. 75°+55°=130°.
18. 40° because angle PSQ is a right angle which means it's 90°. So 130°-90°=40°.
19. 140° because angle ADB is 120° and angle BDC is 20° so 120°+20°=140°.
20. 125° because again it's in the explanation. But if it's a typo and they meant what is the measurement of PSQ then it is 50° because PSR is 125° and QSR is 75° so 125°-75°=50°.
Hope this helps! :)
Answer:
Total earned(in dollars) 
Step-by-step explanation:
Given:
Michael's hourly rate working as a tutor = $12 per hour
Michael's hourly rate working as a waiter = $10 per hour
Total number of hours worked by Michael for both jobs this month = 92
Let the number of hours Michael works as a tutor this month be
hours.
∴ Number of hours Michael works as a waiter this month will be
hours.
