Question

What is the measure of DE
a: 68
b: 56
c: 85
d: 51

Answer 1

So it looks like we need to find the measure of arc DE from the inscribed angle beside 51 degrees.

Answer 2

The formula should be:
The measure of arc DE is 2 times angle DCE

Answer 3

so the answer would be 56?

Answer 4

We basically have to find angle DCE, and then multiply by 2 to get the length of the arc

Answer 5

I'm looking the other values now for clues

Answer 6

ok
