Step-by-step explanation:
Please find the attached document for explanation
84 square inches divided by 14 inches equals 6
84 divided by 14 = s
(2/3)(30)=20
30+20=50=(x/5)
(50*5)=x=250
hope this helps
Answer:
2.3 hours, or 2 hours & 18 minutes
Step-by-step explanation:
we are trying to find h when d is 56.68, so I replaced d with 56.68

subtract 0.1 from both sides

divide both sides by 24.6
Sum of all adjacent angles is 180°.
3x + 12 + x = 180
4x + 12 = 180
4x = 168
x = 42°

Answer: x = 42°
