The isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent. That is option D.

An isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite to these sides are congruent.

This is because the two side of the triangle are identical leading to the angles opposite them being equal too.

Therefore, the isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent.

Answer:

The answer is 29.

Step-by-step explanation:

The steps to do this :

[tex] {c}^{2} = {20}^{2} + {21}^{2} [/tex]

[tex] {c}^{2} = 841[/tex]

[tex]c = \sqrt{841} [/tex]

Given:

Point (a,b) lies on the graph [tex]y=f(x)[/tex].

To find:

The point which is must be lies on the graph of [tex]y=f^{-1}(x)[/tex].

Solution:

According to the definition of an inverse function, if a function is defined as

[tex]f=\{(x,y):x\in R,y\in R\}[/tex]

then, its inverse is defined as

[tex]f^{-1}=\{(y,x):x\in R,y\in R\}[/tex]

It means, we have to interchange x and y-coordinate of the points which lies on the function f to get f⁻¹.

We have a point (a,b) lies on the graph [tex]y=f(x)[/tex]. So, (b,a) must be lies on the graph of [tex]y=f^{-1}(x)[/tex].

Therefore, the correct option is (1).

By the definition of inverse function,the point (a,b) lies on the graph [tex]\bold{y= f(x).}[/tex] So, (b,a) must be lies on the graph of [tex]\bold{y=f^{-1} (x)}[/tex].

Given:

Point (a,b) lies on the graph y= f(x).

Find:

The graph of  [tex]\bold{y=f^{-1} (x)}[/tex] must contain that point.

As per the definition of inverse function, if two one-to-one functions f(x) and g(x). If (f∘g)(x)=x and (g∘f)(x)=x. Then, we say that f(x) and g(x) are inverses of each other.

[tex]\bold{f=\{ (x,y):x\epsilon R,y\epsilon R\}}[/tex]

Then, its inverse is defined as

[tex]\bold{f^{-1} =\{ (y,x):x\epsilon R,y\epsilon R\}}[/tex]

Therefore, we have to interchange x and y-coordinate of the points which lies on the function f to get f⁻¹.

Thus, the point (a,b) lies on the graph [tex]y= f(x).[/tex] So, (b,a) must be lies on the graph of [tex]y=f^{-1} (x)[/tex].

Answer:

56cm

Step-by-step explanation:

5488 is the area of the rectangle.

we know that length x width = area

so to find the with we do area/length

so, 5488/98 =56

Answer:  56 cm

Step-by-step explanation:

Area (A) = Length (L) × width (w)

Given: A = 5488 cm²,  w = 98 cm

    A  = L × w

5488 = L × 98

   56 = L              Divided 98 from both sides

Answer:

Step-by-step explanation:

T = 4 + 2A

S = 5A - 8

T = S

Since T and S are equal, set them against each other

2A + 4 = 5A - 8

Subtract 2A from each side, and add 8 to each side

12 = 3A

Divide each side by 3

A = 4

If Andrew is 4, then Tom is twice that plus 4, or 12. Sarah is 5 times 4 less 8, or 12.

one hundred  seven thirteen and forty nine hundreds standard form

Step-by-step explanation:

Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.

y-intercept:  ( 0 , − 2 )

Step-by-step explanation:

To find the y-intercept, substitute in  0  for  x  and solve for  y

Answer:

(0,-2)

Step-by-step explanation:

Start with:

[tex]2x-5y=10[/tex]

We are going to want this equation in slope-intercept form.

[tex]y=mx+b[/tex]

[tex]mx=slope[/tex]

[tex]b=y-intercept[/tex]

To get the equation in slope intercept from, start by subtracting [tex]2x[/tex] from both sides of the equation:

[tex]-5y=-2x+10[/tex]

Now, divide both sides of the equation by [tex]-5[/tex]:

[tex]y=-\frac{2}{5}x -2[/tex]

[tex]b=-2[/tex]

[tex](0,-2)[/tex]

Answer:

400+4n ≥ 750; The club will need to raise an average of $87.50 or more per month.

Step-by-step explanation:

The inequality will be 400+4n ≥ 750 and the club will need to raise an average of $87.50 or more per month.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.

Given that a school chess club needs to raise at least $750 to attend a state competition. The club has already raised $400 and there are 4 months remaining until the competition.

The inequality will be written as,

400+4n ≥ 750

4n ≥ 750 - 400

4n ≥ 350

n ≥  350 / 4

n ≥  $87.5
