Find the value of x in the triangle shown below.​
nika2105 [10]

Answer:

x =  \sqrt{28}

Step-by-step explanation:

Given,

Base of the triangle = 6

Hypotenuse of the triangle = 8

Let the height of the triangle = x

Therefore, According to Pythagoras Theorem,

{8}^{2}  -  {6}^{2}  =  {x}^{2}

=  > 64 - 36 =  {x}^{2}

=  > 28 =  {x}^{2}

=  > x =  \sqrt{28} (ans)

For which value of x is the equation 3(x+2)+x=2x+16 true?
Arturiano [62]

Answer:

1) take the first part of the equation and work it by multiplying (x+2) by 3

3(x+2)+x

3x +6+x

2)put the answer you got into the question you were given

3x + 6+x =2x +16

3)group the x variables and the non x variables

3x +x -2x =16 -6

4) Now work the equation you have

3x+x-2x=16-6

4x-2x=16-6

2x=16-6

2x=10

5) you divide both sides by the x variable

2x=10

2x/2 =10/2

x=5

therefore x is 5

Does a=2.1 b=7.2 c=7.5 form a right triangle
Anna007 [38]

Answer:

Yes

Step-by-step explanation:

If the longest side squared is equal to the sum of the squares on the other 2 sides then they form a right triangle

longest side = 7.5

7.5² = 56.25

2.1² + 7.2² = 4.41 + 51.84 = 56.25

Thus the 3 values form a right triangle.
