Step-by-step explanation:

y is easy.

it is the Hypotenuse (baseline) of the small right-angled triangle created by the height (8) of the main triangle, the segment 6 of the main Hypotenuse and y.

so, Pythagoras :

y² = 8² + 6² = 64 + 36 = 100

y = 10

x is a bit more complex.

I think the easiest way to get it is to know that the height of a right-angled triangle to the Hypotenuse is the square root of the product of both segments of the Hypotenuse.

so, if we call the segments of the Hypotenuse a and b with a = 6, we have

x = a + b = 6 + b

height (8) = sqrt(a×b) = sqrt(6b)

therefore,

6b = height² = 8² = 64

b = 64/6 = 32/3 = 10 2/3 = 10.66666666...

so,

x = 6 + 10.66666... = 16.666666666...

round it to what is needed. e.g. 2 positions after the decimal point (hundredths) ? then it would be 10.67

Find the value of x in the isosceles triangle shown below.<br> 2<br> 2<br> 5<br> 8

Veronika [31]

Answer:

$\sqrt{41}$

Step-by-step explanation:

think of this triangle being made up of 2 triangles with the lengths of 5, 4, and x.

x being the hypotenuse, 5 being one of the legs, and 4 being one of the legs. (8/2).

pythagorean theorem:

a^2 + b^2 = c^2

5^2 + 4^2 = x^2

25 + 16 = x^2

41 = x^2

x = sqrt 41

The perimeter of the square kitchen floor measures 48 feet. What is the area of the kitchen floor? A. 32 feet B. 96 square feet

exis [7]

Answer:

C. 144 square feet

Step-by-step explanation:

step 1

we know that

The perimeter of a square is given by the formula

$P=4a$

where

P is the perimeter

a is the length side of the square

we have

$p=48\ ft$

substitute in the formula

$48=4a$

solve for a

divide both sides by 4

$a=12\ ft$

step 2

Find the area

The area of a square is given by the formula

$A=a^2$

we have

$a=12\ ft$

substitute

$A=12^2=144\ ft^2$

igomit [66]

Answer:

$\frac{d}{dx}[f(x)+g(x)+h(x)] = \frac{9\cdot x^{8}}{\sqrt{1-x^{18}}} - 81\cdot x^{80}-2\cdot x$

Step-by-step explanation:

This derivative consist in the sum of three functions: $f(x) = 81\cdot \sin^{-1} x^{9}$ , $g(x) = - x^{81}$ and $h(x) = - x^{2}$ . According to differentiation rules, the derivative of a sum of functions is the same as the sum of the derivatives of each function. That is:
