A=16, c=14 find the length of b if necessary round to the nearest tenth

Mathematics
1 answer:
Alex2 years ago

Answer:

None

Step-by-step explanation:

Assuming you mean sides of a right triangle,  we can use the Pythagorean theorem (A^2 + B^2 = C^2)

We have A and B, so we can plug those into the equation.

(16)^2 + B^2 = (14)^2

(16)^2 is 256 and (14)^2 is 196.  Plug those in.

256 + B^2 = 196

Get rid of the 256 by subtracting.

B^2 = 196 - 256

B^2 = -60

√B^2 = √-60

You can't take the square root of a negative number, so the solution is not possible.  We can confirm because C cannot be bigger than A or B.

Through which angle of rotation does the image of a regular pentagon coincide with its preimage?
Svetach [21]
Answer: 72° or any muliple of it: 72°, 144°, 216°, 288°, 360°, ...

It can be either clockwise or counterclockwise.


Explanation:


Thi is because a regular pentagon has 5 congruent sides.

Then you determine the angle of rotation by dividing 360° (a complete turn) by the number of sides (5)

360° / 5 = 72°.

Then every 72° the segments of the image will overlap those of the preimage.

A construction worker needs to determine the volume of a sandpille in a construction yard as shown
postnew [5]
Answer:
6580cm
Step-by-step explanation:
The answer is 6580cm because....
Step one First let's figure out what the smaller shape's volume is. To do so we need to multiply ( LxWxH ) so 6x5x? it does not list what the height is so we know it has the same height as the larger shape and it's height is 14cm so we will use 14cm. 6x5x14=420cm
Step two Now lets find the Volume of the larger shape. So lets do LxWxH so Lx?x14 it does not give us the length so we need to add up all of the numbers along the line. We got 7cm then 5 from the bottom of the smaller shape and 10cm. all ads up to 22cm so 20x22x14=6160
Finally we add up the following shapes Volume which are 6160+420=6580cm
