Answer:

See below.

Step-by-step explanation:<

< DAC and < BCA are alternate angles. So as they are congruent the 2 sides AD and BC are parallel.

Similarly as < BAC and DCA are congruent the sides AB and DC are parallel, so ABCD is a parallelogram.

Therefore as its opposite sides are congruent and AC is common to both triangles, triangle s ABC and CDA are congruent by SSS.

PLS HELP I NEED THIS DONE BY TODAY!!!

Goshia [24]

Answer:

10.08

Step-by-step explanation:

In $\triangle ABC,\: m\angle ACB =90\degree$

$\implies \triangle ABC$ is a right triangle, in which side AB is hypotenuse and sides AC and BC are mutually perpendicular.

By using Pythagoras theorem:

$AC^2 = AB^2 - BC^2 \\ \\ = {(11)}^{2} - {(4.4)}^{2} \\ \\ = 121 - 19.36 \\ \\ = 101.64 \\ \\ \implies \: AC= \sqrt{101.64} \\ \\ \huge\implies \: \red{AC=10.08}$
