The answer to this is 2.
There are a number of proofs to this. Here, we use Euclidean geometry with trigonometry. If we let the center of the circle to be O.
Then, we have the following equations for the angles
CEO = OED = 90
Since, CO = OD because they're radii of the circle, then
ΔCOD is an isosceles triangle and
OCE = ODE
CE + DE = CD
dividing the whole equation by DE
CE/DE + 1 = CD/DE
Using trigonometric functions:
CE = OC cos OCE and
DE = OD cos ODE
Substituting.
OC cos OCE / OD cos ODE + 1 = CD/DE
Since, OCE = ODE,
cos OCE = cos ODE
The equation would be reduced to:
1 + 1 = CD/DE
CD/DE =2
Answer:
The coefficient 6 in 6x means 6(x) or 6 multiplied by x 6 times.
Step-by-step explanation:
X could be anything, it is only holding the place of a number. The coefficient 6 before the x is a number being multiplied by the unknown variable, x. For example if x = 2 the expression would turn into 6(2) which equals 12.
Hope this helps! If you have any other questions please don't hesitate to ask me or your teacher so you can be sure to master the subject. :)

Answer:
Hey dude!
The answer is
area of triangle AED=
AE x DE
How I got this answer:-
Area of a triangle is
base x altitude.
Here, the base of the triangle is DE
And its altitude is AE
Hence, the area would be:-
AE x DE
