Find the missing measurements of the parallelogram Angle DEC=
Angle CDE=
Angle ECD=
Angle DFE=

DEC= 63

CDE=42

ECD= 71

DFE=21

Step-by-step explanation:

I think?

use vertical angles, angle bisector theorem and the fact that all angles add up to 180.

answer: on kudzu, being female and being green are independent events.

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
