Answer:

No triangles are possible.

Step-by-step explanation:

Given:

m∠A = 18°
side c = 19 in
side a = 4 in

In a triangle ABC:

A, B and C are the interior angles.
a, b and c are the sides opposite the corresponding interior angles.

The interior angles of a triangle sum to 180°.

Given m∠A = 18°, the sum of angles B and C is:

⇒ m∠B + m∠C = 180° - 18° = 162°

As there is no answer option where the sum of angles B and C equals 162°, no triangles are possible from the given answer options.

The area of the regular hexagon is 169.74 ft2 what is the perimeter, rounded to the nearest tenth

Bess [88]

Answer:

Perimeter of given regular hexagon is 48.5 ft.

Step-by-step explanation:

Let ABCDEF be the regular hexagon as shown in the attached figure.

O be the intersection point of the diagonals EB, FC and AD.

As per the property of regular hexagon, all the 6 triangles formed are equilateral triangles.

In other words,

$\triangle EOD, \triangle DOC, \triangle BOC, \triangle AOB, \triangle AOF , \triangle FOE$ are equilateral $\triangle s$ .

Area of an equilateral $\triangle$ is defined as :

$\dfrac{\sqrt{3}}{4} \times a^{2}$

Where a is the side of $\triangle$ .

Area of hexagon = $6 \times \dfrac{\sqrt{3}}{4}\times a^{2}$

We are given that area of hexagon = 169.74 $ft^{2}$

Let s be the side of hexagon.

$\Rightarrow 6 \times \dfrac{\sqrt{3}}{4}s^{2} = 169.74 ft^{2}\\\Rightarrow s = 8.08 ft$

A regular Hexagon is made up of 6 equal sides, so

Perimeter of a regular hexagon = $6 \times side$

Perimeter = $6 \times 8.08$

$\Rightarrow 48.5 ft$

So, perimeter of given regular hexagon is $48.5 ft$ .

Vhat is the inverse of the function f(x) = 2x – 10?

olchik [2.2K]

To find the inverse of a function, replace x and y in the equation and solve for y. In our case...

x=2y-10
x+10=2y
y=x/2+5

A number is multiplied by 8, and that product is added to 2. The sum is equal to the product of 2 and 25. Find the number.

LenKa [72]

Answer: the number = 6

Step-by-step explanation:

Let x be the number.

Set equation according to the information given

2 + 8x = 2 × 25

Simplify by multiplication

2 + 8x = 50

Subtract 2 on both sides

2 + 8x - 2 = 50 - 2

8x = 48

Divide 8 on both sides

8x / 8 = 48 / 8

$\boxed {x=6}$

Hope this helps!! :)
