Calculate JK if LJ=45, JM=60 and LM=75
aliina [53]

Answer:

JK = 20

Step-by-step explanation:

Angle Bisector Theorem: an angle bisector of a triangle divide the opposite side into two segments that are proportional to the other two sides of the triangle

LK / JK = LM / JM

(45 - JK) / JK = 75 / 60 = 5 / 4

5 JK = 4 (45 - JK)

5 JK = 180 - 4 JK

9 JK = 180

JK = 20

Percentage Increase:     (75 - 60) / 60   * 100%

= 15/60 * 100%

= 1/4   * 100%

= 0.25 * 100%

= 25%

- 2x – 117 = = 10x + 59
Alexxx [7]

Answer:

\huge\boxed{x=-\dfrac{44}{3}=-14\dfrac{2}{3}}

Step-by-step explanation:

-2x-117=10x+59\qquad|\text{add 177 to both sides and subtract}\ 10x\ \text{from both sides}\\\\-2x-10x-117+117=10x-10x+59+117\\\\-12x=176\qquad|\text{divide both sides by (-12)}\\\\\dfrac{-12x}{-12}=\dfrac{176}{-12}\\\\x=-\dfrac{176:4}{12:4}\\\\x=-\dfrac{44}{3}

Of the three properties, reflexive, symmetric, and transitive that define the relation "is equal to," which one could also apply
yan [13]

Answer: Transitive property.

Step-by-step explanation:

First, for the equality we have:

Reflexive:

  For all real numbers x, x = x.

Symmetric:  

 For all real numbers x, y

 if x= y, then y = x.

Transitive:

 For reals x, y and z.

 if x = y, and y = z, then x = z.

Now, let's talk about inequalities.

first, the reflexive property will say that:

x > x.

This has no sense, so this property does not work for inequalities.

Now, the reflexive.

If x > y, then y > x.

Again, this has no sense, if x is larger than y, then we can never have that y is larger than x. This property does not work for inequalities.

Not, the transitive property.

if x > y, and y > z, then x > z.

This is true.

x is bigger than y, and y is bigger than z, then x should also be bigger than z.

x > y > z.

And this also works for the inverse case:

x < y and y < z, then x < z.

So the correct option is transitive property.
