Find AE in the parallelogram, if BD = 12, and AC = 18
Liono4ka [1.6K]
See the picture in the attached figure

we know that

There are six important properties of parallelograms to know:

<span>1) Opposite sides are congruent (AB = DC).
2) Opposite angels are congruent (D = B).
3) Consecutive angles are supplementary (A + D = 180°).
4) If one angle is right, then all angles are right.
5) The diagonals of a parallelogram bisect each other.
<span>6) Each diagonal of a parallelogram separates it into two congruent triangles.

so
if t</span></span>he diagonals of a parallelogram bisect each other
then 
AE=EC
AC=AE+EC------> AC=2*AE----> AE=AC/2----> AE=18/2----> AE=9 units

the answer is
AE=9 units

Which of the listed values are equal to the sine of C A.)b/a B.)c/a C.)c/b D.)cos B E.)5.Cos C F.)cos (90°-C) G.)cos(90°-B)
kherson [118]

Answer:

Sine of C=?

Among the given options which is the correct one.

Step-by-step explanation:

Consider a right-angle triangle ABC.

angle B=90^{0}

In a right angle triangle, one angle 90^{o}.

The sum of all the angles is 180^{o}.

angle A +angle B+angleC=180^{0}angleA+90^{0} +angle C=180^{0}\\angleA+angleC=180^{0} -90^{0} \\angleA+angleC=90^{0} \\angleA=90^{0} -angle C

Consider the trigonometric ratios and use the traingle ABC.

SinC=\frac{AB}{AC}

CosA=\frac{AB}{AC}

angleA=angle(90-C)\\Hence,\\SinC=Cos(90-C)

Answer:

OptionF).Sine  of  C=Cos(90^{0} -C)
