Word problem: Today the temperature dropped 13 °F. After this drop, the temperature was 74 °F. What was the original temperature outside before the drop?
Subtraction problem: x °F - 13 °F = 74 °F

Answer:
Step-by-step explanation:
you know that both angles=180
6x+20+2x+4=180
8x+24=180
8x=180-24
8x=156
x=19.5
angle TQS=19.5*60+20=137
angle SQR=2*19.5+4=43
