Please help answer this​
julsineya [31]

Answer:

4.8 units^2

Step-by-step explanation:

Hello!  To find the area of this triangle, we need to know both the base and the height.  Neither is specifically given.  

We can find the height (CD) as follows:

3^2 - 1.8^2 = 5.76, so CD has the length sqrt(5.76) = 2.4.

Triangles ACD and ABC are similar.  Therefore, the following equatin of ratios holds:

1.8       CD       2.4

----- = ------- = --------

3.0      AB        AB

Then 1.8AB = 3.0(2.4), or AB = 7.2/1.8 = 4.

So the height of triangle ABC is 2.4 units and the length of the base is 4 units.

Therefore, the area of this triangle is A = (1/2)(base)(height), or

A = (1/2)(4 units)(2.4 units) = 4.8 units^2

Which best explains if quadrilateral WXYZ can be a parallelogram?
Burka [1]

Answer:

WXYZ is not necessary a parallelogram it is unkown if WC = CY.

Step-by-step explanation:

Given : Quadrilateral WXYZ .

To find : Which best explains if quadrilateral WXYZ can be a parallelogram.

Solution : We have given that quadrilateral WXYZ .

Given diagonal bisect XZ :   CZ = CX

By the property of parallelogram : The diagonals bisect each other.

But we do not have WC = CY

To be a parallelogram it must be  equal WC = CY

Then we can not say WXYZ is a parallelogram.

Therefore, WXYZ is not necessary a parallelogram it is unkown if WC = CY.

Need some help using some type of formula for this.
Romashka-Z-Leto [24]
This is about the weight per volume unit.

Item A has a volume of 4*5*2 = 40 ft3 and it weighs 1000 lbs.
That is 1000/40 = 25 lbs/ft3, which makes it a class 3 item.

Does that make sense to you? Can you do the rest now?
