Answer:

  a.  12 cm

  b.  90°

  c.  60°

Step-by-step explanation:

The relevant relationships are ...

  • all sides of a rhombus have the same length
  • the diagonals of a rhombus are perpendicular bisectors of each other
  • the diagonals of a rhombus divide the figure into 4 congruent triangles

__

a) The perimeter, 48 cm, is the sum of four equal side lengths, so any given side is (48 cm)/4 = 12 cm.

  GH = 12 cm

__

b) Angle EJF is where the diagonals meet. It is a right angle.

  ∠EJF = 90°

__

c) Angle EFJ is the complement of the one marked, so is 30°. Angles EHJ and GHJ are congruent to that, so both are 30°. Angle EHG is the sum of those two congruent 30° angles, so is ...

  ∠EHG = 60°

Ostrovityanka [42]

Answer:

Hey there!

A "flip" can be considered a reflection.

A "spin" is a rotation.

A "slide" is a translation.

None of these transformations change the way a shape looks, or the size of the shape. They only change how the shape is oriented.

Let me know if this helps :)

Answer:

Unusual

Step-by-step explanation:

Given that a tobacco company claims that the amount of nicotine in its cigarettes is a random variable with mean 2.2 mg and standard deviation .3 mg.

i.e. population parameters are

\mu =2.2 \\s = 0.3

The approximate probability that the sample meanwould have been as high or higher than 3.1

=P(X\geq 3.1)\\=P(Z\geq \frac{3.1-2.2}{\frac{0.3}{\sqrt{100} } } )\\=P(Z\geq 30)\\

=0.0000

The lenght of one <br><br> plz answer right show work or describe
Natasha2012 [34]
Since its a right triangle, you can use a² + b² = c²
one of the legs is a and the other leg is b it doesn't matter which one because its addition and works the same way c needs to be the hypotenuse 

so its a² + 48² = 50²
a² + 2304 = 2500
    - 2304    -2304
          a² =  196
      √a² = √196
         a = 14
