Me i need it in five minutes and also show your work

We know that there is 180 degrees in a triangle. Also, we know that a line has a total of 180 degrees across it. With this, we can find Angle C.

First, let's find Angle ACB

70 + 30 + x = 180 (because 180 in a triangle)

100 + x = 180

X = 80

Now that we know angle ACB, we can use that to find Angle BCE.

80 + Y (Angle BCE) = 180 (because 180 along a line)

Y = 100

So Angle BCE is 100 degrees.

I hope this Helps!
