Area of sector



so the area = 37.71 square metre
Angle B=180-(38+31.6)=110.4
by law of sin
sin B/b=sinA/A
sin(110.4)/b=sin38/25
b=25*sin(110.4)/sin(38)=38.06
I think it would be 3.19.
Dividing 25.52 by 8.
Set up the equation ... 60 + 40X = total charges... where X is the number of hours (8.5)
60 + 40(8.5) = ?
60 + 340 = ?
400 = total charges
Answer:
yes the graph reflects over the y-axis because if you see in the y axis the line show that it is the pont to the axis
hope it helps
