the picture in the attached figure

we know that

if ABC is an isosceles triangle

then

AB=BC

angle A=angle C=45 degrees

and

triangle ABD and triangle BDC also are isosceles triangles

AD=BD=x

DC=BD=x

the hypotenuse AC is equal to

AC=AD+DC\\ AC=x+x\\ AC=2x

To find the length AB applying the Pythagorean Theorem

AC^{2} =AB^{2} +BC^{2}

remember that AB=BC

AC^{2} =2AB^{2}

AC^{2} =2AB^{2}\\\\ AB=\frac{AC}{\sqrt{2}}\\\\ AB=\frac{2x}{\sqrt{2}}\\\\ AB=x\sqrt{2}

therefore

the answer is

the length of one leg of the large right triangle in terms of x is equal to x\sqrt{2}

What is a rational expression R(x)​
kiruha [24]

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.

Cerrena [4.2K]

Answer:

113/24

Step-by-step explanation:

Simplify the following:

(14 + 1/8)/3

Put 14 + 1/8 over the common denominator 8. 14 + 1/8 = (8×14)/8 + 1/8:

((8×14)/8 + 1/8)/3

8×14 = 112:

(112/8 + 1/8)/3

112/8 + 1/8 = (112 + 1)/8:

((112 + 1)/8)/3

112 + 1 = 113:

(113/8)/3

113/8×1/3 = 113/(8×3):

113/(8×3)

8×3 = 24:

Answer: 113/24

An angle of -210 degree is in standard position. What are the coordinates of the point at which the terminal side intersects the
Lunna [17]

Answer:

( -\sqrt{3}/2 , -1/2)

Step-by-step explanation:

-210 degrees in standard position corresponds to an angle in the 3rd quadrant  30 degrees below the negative x-axis

The hypotenuse of the triangle here is 1, and we want the coordinates.

PLEASE PLEASE I SUCK AT MATH AND ITS ALL DUE FRIDAY PLEASE 10 piont !!! Select all the correct systems of equations.
alekssr [168]

Answer:

2x + y = 17

-6x = 3y - 51

Step-by-step explanation:

You get an infinite number of solutions when two equations are really just the same. This means you can convert one into the other simply by multiplying one to get the other.

In the above answer, if you multiply the above by -3 you get:

-6x -3y = -51

which is of course -6x = 3y - 51

So that is an example of a pair that has infinite solutions.

To find all of them, you'd carefully have to compare each 2 and see if there is a multiplier to convert one into the other. You can do that!
