First we need to find the missing side, use

a =  \sqrt{ {c}^{2} -  {b}^{2}  }
So the missing leg = the sqrt of the hypotenuse squared minus the other leg squared.

Let's substitute the numbers,

a =  \sqrt{ {10}^{2}  -  {6}^{2} }
Solve for the squares,

a =  \sqrt{100 - 36}
Subtract,

a =  \sqrt{64}
Solve for the root,

a = 8
~~

So our missing length is 8.

To find the perimeter of the triangle, simply add all the sides....

~~

8 + 10 + 6 = 24

~~

Answer : 24

~~

I hope that helps you out!!

Any more questions, please feel free to ask me and I will gladly help you out!!

Answer:  The perimeter of the triangle given is:  " 24 units " . 
______________________________________________________
Explanation:
______________________________________________________
        To find the perimeter of the triangle, we add up the lengths of
  all 3 (THREE) sides of the triangle; and we have the answer!
______________________________________________________
The triangle given is a "right triangle.

We are given the length of 2 (TWO) of the sides:  "6 units" ; and "10 units (the length of the hypotenuse). 
___________________________________________________________
We can find the "unknown side length" by using the "Pythagorean theorem" (since this is a "right trangle"):

       →   a²  +  b²  = c²  ;  

                          in which : "c" is the hypotenuse; which is:  "10" (given); 

Let "b" represent the known side length, which is "6" (given). 

Solve for "a" (the "unknown" side length).

         →  a²  +  6²  =  10²  ;   Solve for "a" ;

         →  a²  =  10²  –  6²  = 100 – 36 = 64 .

         ↔  a² = 64 . 

Now, take the positive square root of each side of the equation; 
      to isolate "a" on one side of the equation; & to solve for "a" ; 

         →   ⁺√(a²) = √64 ; 

         → a = 8 .
__________________________________________________
Now, to find the "perimeter" of the triangle, we add up all of the side lengths:

   6 + 8 + 10 =  14 + 10 = 24 . 
__________________________________________________
Answer:  The perimeter of the triangle given is:  " 24 units " .

What are the two things that happen to water molecules when heat energy is added to air?
yuradex [85]

Answer:

When the heat is raised (for instance, as water is boiled), the higher kinetic energy of the water molecules causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas. We observe this gas as water vapor or steam.

a jar contains 36 marbles. it has 20 red, 12 black, and 4 green marbles. two marbles are drawn; the first is not returned before
Igoryamba
P(red) first drawn:
20/36=5/9
P(red) second drawn:
19/35

95/315 or 19/63. As a result, the probability that both marbles are red is 19/63. Hope it help!

If a hexagon is worth 5 and a triangle is worth 3, what is a circle
Olegator [25]

Answer:

6

Step-by-step explanation:

Call pentagon p, circle c and triangle t

We have 2c + 2p = 2p + 2t + c

p = 5, t = 3 so

2c + 2(5) = 2(5) + 2(3) + c

2c + 10 = 10 + 6 + c

2c = 6 + c

c = 6
