If polygon a is a parallelogram, and polygon b is a rectangle, which of the

The answer is C

Step-by-step explanation:

* Lets talk about some facts in parallelograms and rectangles

- Rectangle is a parallelogram with right angles

- Supplementary angles is two angles their sum is 180°

- The opposite angles in the rectangle are equal and supplementary

- A circle can circumscribe a quadrilateral if the opposite angles of

 the quadrilateral are supplementary

- In the parallelograms opposite angles are equal

- The circle can circumscribe a rectangle because its opposite

 angles are supplementary

- The circle can't circumscribe a parallelogram because its opposite

 angles are not supplementary they are equal

* Lets solve the problem

- Polygon A is a parallelogram

- Polygon B is a rectangle (parallelogram with right angles)

∵ The circle can't circumscribe a parallelogram because its opposite

  angles are not supplementary

∴ Polygon A can't circumscribed by a circle

∵ Polygon B is a rectangle its opposite angles are equal the measure

  of  each one is 90°

∴ Its opposite angles are supplementary

∴ Polygon B can circumscribed by a circle

∵ The rectangle is a parallelogram with right angles

∴ Polygon B represents the only parallelogram that a circle can

  circumscribed because opposite angles are supplementary

* The answer is C

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
