Hey i know this question is linked to Pythagorean theorem but i am still confused. So, please help me if you can ❤️
antiseptic1488 [7]

Step-by-step explanation:

From Pythagorean theorem, one of the sides can be determined as x^2 + y^2 =8^2

or y = (8^2 - x^2)^(1/2)

we can write the perimeter P as

P = 2x + 2y ---> 20 = 2x + 2(8^2 - x^2)^(1/2)

Dividing by 2, we get

10 = x + (8^2 - x^2)^(1/2)

Move the x to the other side,

10 - x = (8^2 - x^2)^(1/2)

Take the square of both sides to get rid of the radical sign:

(10 - x)^2 = 8^2 - x^2

Move everything to the left and expand the quantity inside the parenthesis:

x^2 + (100 - 20x + x^2) - 64 = 0

2x^2 - 20x + 64 = 0

or

x^2 - 10x + 32 = 0

Now we can see that a = -10 and b = 32

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)
