Answer:

√185

Step-by-step explanation:

(x₁,y₁)= (-4,6)

(x₂,y₂)=(7,-2).

the length of the line AB =√{(x₂-x₁)²+(y₂-y₁)²}

                                         =√[{7-(-4)}²+{-2-6}²]

                                          =√[{7+4}²+{-2-6}²]

                                          = √{11²+(-8)²}

                                          =  √121+64

                                          =√185

Answer:

√185 or 13.60 units to the nearest hundredth.

Step-by-step explanation:

For the points (x1,y1) and (x2,y2) the length between the points is given by:

L = √ [ (x2-x1)^2 + (y2-y1)^]

So here we have:

Length of AB  √ [ (7- - 4)^2 + (-2 - 6)^2]

=  √ (121 + 64)

= √185.

What is the measure of c?<br> a = 15<br> j = 24<br> k = 32
inessss [21]

Answer:

The answer to your question is c = 20

Step-by-step explanation:

Data

a = 15

j = 24

k = 32

c = ?

Process

Use proportions to solve this problem. Compare the small triangle and the large triangle.

1.- Proportion of the small triangle

             c/15

2.- Proportion of the large triangle

            k/j

3.- Equal but terms and solve for c

            c/15 = k/j

-Substitution

            c / 15 = 32/24

            c = 32(15)/24

-Result

            c = 20

Solve for b:<br> a/b = c
irina [24]


Multiply each term by
b

and simplify.
a = cb

Rewrite the equation as
cb = a
Divide each term by
c

and simplify.
b = a/ c

Can a triangle be formed with side lengths:<br> 10, 12, 22
Elenna [48]
No. A squared plus b squared must equal c squared (Pythagorean theorem). 10 squared is 100, 12 squared is 144, they add up to 244 but 22 squared is 484…..much too large
