Shelly bought new earrings. She measured them to see how long they were. They were between 4.6 cm. And 4.9 cm. Long. What could be the length of her earrings?

Answer:

Step-by-step explanation:

a = b

Pythagorean Theorem:

b = 10/√2

The value of a and b is   [tex]\frac{10}{\sqrt{2} }[/tex]   .

Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle.

The basic trigonometric ratios formulas are given below,

sin θ = Perpendicular/Hypotenuse

cos θ = Base/Hypotenuse

tan θ = Perpendicular/Base

sec θ = Hypotenuse/Base

cosec θ = Hypotenuse/Perpendicular

cot θ = Base/Perpendicular

According to the question

Hypotenuse of right angle triangle = 10

Base of  of right angle triangle  = a

Perpendicular  of right angle triangle = b

Now,

By using trigonometric ratios  

sin θ = Perpendicular/Hypotenuse ---------(1)

substituting the values in equation (1)

sin 45° =  [tex]\frac{b}{10}[/tex]

[tex]\frac{1}{\sqrt{2} }[/tex]  = [tex]\frac{b}{10}[/tex]  

b = [tex]\frac{10}{\sqrt{2} }[/tex]  

cos θ = Base/Hypotenuse

cos 45° = [tex]\frac{a}{10}[/tex]

[tex]\frac{1}{\sqrt{2} }[/tex]  = [tex]\frac{a}{10}[/tex]

a =   [tex]\frac{10}{\sqrt{2} }[/tex]  

Hence, The value of a and b is   [tex]\frac{10}{\sqrt{2} }[/tex]   .

Answer:

There are no reflectional symmetries.

Step-by-step explanation:

Hi there, a reflectional symmetry requires the reflection to mirror that of the figure being reflected. To put it in simpler terms, it should look exactly the same if you put one half right next to a mirror.

I hope this clears up things a bit.

The required, latter F does not have reflectional symmetries.

Reflection symmetry is a type of symmetry where a figure is reflected across a line, called the line of symmetry, and the resulting figure is identical to the original. In other words, if you were to fold the figure along its line of symmetry, the two halves would match up perfectly.

Since we have given the figure of latter F, which does not have reflectional symmetries.

It's important to note that not all letters have reflectional symmetry, but the letter "F" is one example of a letter that does have this type of symmetry.
