Find the measure of the third side of the triangle given the measures of two sides.6ft and 19ft

I don't know how to get the third side.

Answers

Knowing the length of 2 sides is not enough to nail down the length of the
third side.  There are an infinite number of possibilities that it could be.

Here's what you have now:  You have two sticks.  One of them is 6-ft long,
and the other one is 19-ft long, and they're joined together at one end
with a hinge.  You can open them wide, or you can close them down to
a narrow slit.  Whatever you do with them, you can always join their
other ends with another stick.  It may be short, or it may have to be
long.  Knowing the lengths of the first two sticks doesn't tell you the
length of the stick you need in order to make a triangle.

(So don't feel too bad that you don't know how to get the third side.
There isn't a way.)

Final answer:

Without information about the angle between the two sides of the triangle, the third side's length can only be estimated to be between 13 and 25 feet.

Explanation:

In mathematics, you can often use the Pythagorean theorem to find the length of the third side of a triangle. This theorem, which applies to right triangles, states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In your case, however, without any information concerning the angle between these two sides, we cannot determine a unique value for the length of the third side. The third side will have a value that lies between 13 ft and 25 ft, depending on the angle between the two sides.

Can someone help me pls

Answers

Answer:

432 ft^2

Step-by-step explanation:

Answer:

432

Step-by-step explanation:

Lets plug it into the formula

b1 should be the horizontal line on the bottom horizontal line and b2 should be the top horizontal line

so we get b1 = 28 and b2 = 20

according to the formula we should add b1 and b2, getting us 48.

divide 48 by 2: we get 24

24 times h, or the hieght, or 18 is 432

so the answer is 432

If f(x) = 6 – 5x and g(x) = 4x – 1, evaluate f(x) – g(x) for x = –2. A. –11 B. 7 C. 9 D. 25

Answers

Answer:

D. 25

Step-by-step explanation:

f(x) = 6 – 5x and g(x) = 4x – 1

We want to subtract.

f(x) -g(x)= 6 – 5x -( 4x – 1)

Distribute the minus sign

6 – 5x - 4x + 1

I line them up vertically

– 5x +6

 - 4x + 1

-------------------

  -9x +7

Now let x = -2

-9(-2) +7

18+7

17.16 is 62.4% of what

Answers

17.16 is 62.4% of 27.5

Change the percentage (62.4) into a decimal by dividing the percentage by 100:
(62.4)/(100) = 0.624

Divide 17.16 by 0.624:
(17.16)/(0.624) = 27.5
Use is over of equals percent over 100. 17.6 would go where is is, and the percent would go in the place of the percent. Crossmultiply and you should get an answer. If you need me to check message me
