Answer:

Vertical Angles are Congruent

Step-by-step explanation:

Angle BCA and angle DCE are congruent since they are vertical angles. Lines BE and AD cross each other to make vertical angles. You can't really know if BC equals EC for sure, as well as how Alternate Interior Angles are Congruent. I don't know how else I can explain this, but I hoped it helped you understand why it is A = Vertical Angles are Congruent.

Find the ARE of the figure

Tresset [83]

First, break up the shapes into parts. The first one you see is 7 by 4 rectangle on the top.
A=l*w
A=7*4
A=28 for the rectangle, your not done
Now the triangle to the left
A=l*w/2
A=19*10/2
A=95
Now all you got left is the trapezoid, which area's formula is:
A=(b∧1+b∧2*h)/2
A=9+19*8/2
A=112.
Now you have the area for three of the figures, add them up:
112+95+28=235
So in total, the area of this figure is 235 cm^2
