Answer: 6 sqrt2

Step-by-step explanation:

Sqrt = square root shorthand.

In a 45-45-90, the legs can be represented as x and the hypotenuse as x root2.

12 = x (sqrt2)

12/sqrt2 = x

Let’s rationalize this by putting the square root on top:

12sqrt2 / 2

Simplify:

6sqrt2

f(x) = 1/4 to the power of x + 2= 627
f(x) = 1/4 to the power of x + 2= same thing as the one above
f(x) = 1/4 to the power of x - 2= 623
f(x) = 1/4 to the power of x − 2= same thing as the one above

Answer:

$Area = 34.2cm^2$

Step-by-step explanation:

Let the three sides be a, b and c respectively.

Such that:

$a = 8$

$b = 9$

$c= 10$

Required

Determine the area

This is calculated as:

$Area = \sqrt{s(s-a)(s-b)(s-c)$

Where

$s = \frac{1}{2}(a + b + c)$

Substitute values for a, b and c

$s = \frac{1}{2}(8 + 9 + 10)$

$s = \frac{1}{2}(27)$

$s = 13.5$

Substitute values for a, b, c and s in

$Area = \sqrt{s(s-a)(s-b)(s-c)$

$Area = \sqrt{13.5 * (13.5 - 8)* (13.5 - 9)* (13.5 - 10)$

$Area = \sqrt{13.5 * 5.5* 4.5* 3.5$

$Area = \sqrt{1169.4375$

$Area = 34.2$ -- Approximated
