Answer:
Step-by-step explanation:
SSS (Side-Side-Side) Postulate can be used to prove the two triangles congruent.
<u>Here's why:</u>
Whole figure is a parallelogram which means that opposite sides are parallel and equal (or congruent).
So, Two of the sides can be proved congruent by that way.
The third side is common in both of the triangles which means that the third side is also congruent.
Hence, the two triangles are congruent by SSS postulate.

Answer:
The value of DC is 66.34.
Step-by-step explanation:
The triangles ABC and DCA are right angled triangles.
The straight line AC is a bisector for angles C and A.
The measure of ∠C is 30°.
Then the measure of angles BCA and ACD will be 15° each.
The measure of angle DAB is 150°.
Then the measure of angles DAC and BAC will be 75° each.
Now consider the right angled triangle ABC.
The measure of side AC is:
Consider the right angled triangle DCA.
The angle DAC measure 75°.
Using the trigonometric identities compute the value of Perpendicular DC as follows:
Thus, the value of DC is 66.34.
