Angle ADB = 80 degrees

Step-by-step explanation:

This is a parallelogram so:

AD || BC

AB || DC

Using the Alternate Interior Angles Postulate, you can find that:

Angle BDC = Angle DBA

So because Angle BDC is 28 degrees, we know that Angle DBA is also 28 degrees.

Now, we can figure out what angle ADB is using the property of triangles that all the angles of add up to 180:

Angle ADB + 72 + 28 = 180

Angle ADB + 100 = 180

Angle ADB = 80

So, Angle ADB is 80 degrees.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
