It will take 3 months to wire 55 houses. She can wire 18 a month at 4.5 pee week. So you that's roughly 18 a month. 18x3=54 if there is 4 weeks in a month. If you have 5 weeks in the month then it will bend 22 a month. 22x2.5=55 so in this case just 2 and a half months to wire 55 houses at 4.5 houses a week.

Question:
Obtian the equation that can be used to solve for c
Answer:
Sin50 = 3/c
Step-by-step explanation:
A triangle showing the information given has been attached below for clarity :
Using trigonometry :
AC = 3 = opposite side of angle 50°
AB = c = hypotenus
Using the sine relation of a right angled triangle :
Sin θ = opposite / hypotenus
θ = 50°
Sin 50° = 3 / c
Sin50 = 3/c
