Answer:

Hi there!

The correct answer is: 21 m

Step-by-step explanation:

Using the law of cosine: ( c² = a²+ b² − 2ab cos(C) )

In this case the missing side BC, would be represented by "C"

c² = (6.5)² + (21.9)² - (2)(6.5)(21.9)cos(73.5)

simplify and you get c=21 m

So basically plus likes 21.9+73:5=let’s say 5 than your do 6.5+73.5=“788” then 21.9+6.5=“789” (those aren’t the real answers) you do that and do addition the 3 answers together and Multiple by 2

A parallelogram is shown below:
Marina CMI [18]
<h3>Answer:</h3>

A:  6 ft²

B:  3 ft² is the area of each of the two congruent triangles

<h3>Step-by-step explanation:</h3>

Part A. As with a rectangle, the area of a parallelogram is the product of base length and height.

  Area = (8 ft)·(3/4 ft) = 6 ft²

___

Part B. If you cut the area into two halves, each half will have half the area of the original. (That should not be a surprise.)

  triangle area = (6 ft²)/2 = 3 ft²

If the triangles are created by a diagonal across the original figure, each will have a base length and height that is the same as that of the original figure. The area of a triangle is half the product of base and height, so each triangle will have area ...

  triangle area = (1/2)bh = (1/2)(8 ft)(3/4 ft) = 3 ft²

Find the area of the following figure:
stellarik [79]

Answer:

12m

Step-by-step explanation:

You can break this shape down into a square and a trapezoid. Frist you can find the area of the square by multiplying 2 by 5 to get 10. Then you would find the area of a trapezoid by doing Area = 1/2height(base1+base2). We can find the height by subtracting 5 from 9. (We do this because we know the side of the square is 5m) Therefore the height would be 4m. We know the bases are 2 and 4. From there you can plug those numbers in to the formula. Area=1/2 * 4 (2 + 4)

Area= 1/2 * 4 (6)

Area = 2(6)

Area = 12m

Parallelogram ABCD has the angle measures shown. Can you conclude that it is a rhombus, a rectangle, or a square? Explain.
Hoochie [10]

Answer:

The correct option is parallelogram ABCD is a rhombus, because the diagonal bisects two angles

Step-by-step explanation:

In triangle ABD:

∠B = ∠D

Thus AB=AC by the property of opposite sides of equal angles are equal

In triangle CBD

∠B = ∠D

Thus CB=CD  by the property of opposite sides of equal angles are equal

Thus all four sides of quadrilateral ABCD are equal  

And diagonal BD bisects the angles  

So, it is a rhombus

Therefore the correct option is  parallelogram ABCD is a rhombus, because the diagonal bisects two angles....
