Problem: Find Length Of DE

What we know:

CE = 12

DC = 6

We know the length of DC. DC is 5. That is 5 units more than what we need to know, which is the length of DE.

How To Find DE

DE = CE - DC

Insert Numbers Into Equation:

CE = 12 - DC = 5

12 - 5 = 7

DE = 7

Option 4. 7 is the answer.

Step-by-step explanation:

Given parameters are BC = 6, CD = 5, CE = 12

We have to find the length of DE.

Here the length of the segment CD = 5 and length of the secant CE = 12

Therefore the length of DE = CE - CD = 12 - 5 = 7

So DE = 7

Therefore option 4 is the correct answer.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
