Answer:

The answer is below

Step-by-step explanation:

The question is not complete, a complete question is attached.

Solution:

A triangle is a polygon with three sides and three angles. Types of triangles are right angled, obtuse, acute, scalene, isosceles, equilateral triangle.

Trigonometric identities are used to show the relationship between the sides and the angles in a right angled triangle. Below are some trigonometric identities:

sin(θ) = opposite / hypotenuse; cos(θ) = adjacent / hypotenuse; tan(θ) = opposite / adjacent

The hypotenuse is the longest side in the triangle.

From the image attached:

sin(α) = opposite side / hypotenuse side

sin(α) = 7 / 25

Given that f(x) = 10x + 45, find f(7)

sattari [20]

Answer:

$\boxed{\bf f(x) = 115}$

Step-by-step explanation:

<u>Given polynomial </u><u>function </u>:-

$f(x) = 10x + 45$

<u>To </u><u>find</u> :-

$\sf \: f(7)$

<u>Solution:-</u>

$\sf \implies \: f(x) = 10x + 45$

Here, the value of x is 7(given).

So, <u>Substitute the value of x on the RHS and </u><u>on </u><u>LHS </u>:-

$\sf \implies{f}(“7”) = 10(“7”) + 45$

Simplify the RHS:-

<u>Multiply 10 and 7 :-</u>

$\sf \implies{f}(7) = 10 \times 7 + 45$

$\sf \implies{f}(7) = 70 + 45$

<u>Add 70 and 45 :-</u>

$\sf \implies{f}(7) = 115$

We're done!

Hence, the value of f(7) would be,

$\sf \implies{f}(7) = 115$

$\rule{225pt}{2pt}$

I hope this helps!

If the diagonal of a square is approximately 12.73, what is the length of its sides?

Alja [10]

Answer:

The length of the sides of the square is 9.0015

Step-by-step explanation:

Given

The diagonal of a square = 12.73

Required

The length of its side

Let the length and the diagonal of the square be represented by L and D, respectively.

So that

D = 12.73

The relationship between the diagonal and the length of a square is given by the Pythagoras theorem as follows:

$D^{2} = L^{2} + L^{2}$

Solving further, we have

$D^{2} = 2L^{2}$

Divide both sides by 2

$\frac{D^{2}}{2} = \frac{2L^{2}}{2}$

$\frac{D^{2}}{2} = L^2$

Take Square root of both sides

$\sqrt{\frac{D^{2}}{2}} = \sqrt{L^2}$

$\sqrt{\frac{D^{2}}{2}} = L$

Reorder

$L = \sqrt{\frac{D^{2}}{2}}$

Now, the value of L can be calculated by substituting 12.73 for D

$L = \sqrt{\frac{12.73^{2}}{2}}$

$L = \sqrt{\frac{162.0529}{2}}$

$L = \sqrt{{81.02645}$

$L = 9.001469325$

$L = 9.0015$ (Approximated)

Hence, the length of the sides of the square is approximately 9.0015
