Answer:

Step-by-step explanation:

First take triangle BDH. We know B is 46 degrees and D is 33 degrees. Since the angles of a triangle equal 180 we get
180 - 46 - 33 = 101 for H.
H is supplementary to x, so their sum is also 180. This gives 180 - 101 = 79.
So x is 79 degrees.
Answer:
you would need to give the figure
-3.2b + 9
by adding like terms together.

Step-by-step explanation:
No trapezoid is attached; so, I will solve on a general note
The area of a trapezoid is:

Using the attached image as a point of reference;
The parallel sides are: AD (6cm) and BD (12cm)
The height is 4cm
So, the area is:
