Answer:

I believe (not confident) You take 180-28 and divide that by 2. (76 degrees)

We know that the top angle of the triangle is 28 degrees because vertical angles are congruent.

Answer:

Area is 364

Step-by-step explanation:

A parallelogram's area is equal to base times height. So it doesn't depend on the angle at all, as long as the base and height are constant.

That means that the area of the parallelogram on the left is the same as if it was a rectangle (an extension of the rectangle part on the right).

This brings us to the answer - the area is the same as the area of a 14x26 rectangle.

14*26=364

Alternatively, let's compute the area of the rectangle on the right:

18*14 = 252

And the area of the parallelogram

14 * (26-18) = 14*8 = 112

And the area of the composite figure is 252+112 = 364
