Angle x = 30 degrees
Angle y= 100 degrees
Angle z = 50 degrees
Sum of the angles = 180 degrees
Required equation is y - y1 = m(x - x1); where m = 4 and (x1, y1) = (4, -4)
y - (-4) = 4(x - 4)
y + 4 = 4(x - 4)
we know that property of in center we get
DW = FW = EW
compare the equations and solve for x:
DW = FW
7x - 13 = 15x - 37
15x - 7x = 37 - 13
8x = 24
x=24/8
x = 3
now
DW = 7x - 13 = 7×3 - 13 = 8 units
The measure of WE is same as DW=WE = 8 units
