Answer:all real numbers

Step-by-step explanation: f(x) =3 means that Y is 3 for every value of X, as there's no X affected in the formula, so it will have that value always.

As there are also no restrictions, like 1/X or logX then you know that every value of X is possible to be replaced in f(x) fórmula [if there were any X in the formula, which is not the case]

<u>Given</u>:

The given triangle is a right triangle.

The length of the hypotenuse is 31 units.

The length of the leg is 23 units.

One of the angle is x.

We need to determine the value of x.

<u>Value of x:</u>

The value of x can be determined using the trigonometric ratio.

Thus, we have;

sin \ \theta=\frac{opp}{hyp}

Substituting \theta=x, the side opposite to the angle x measures 23 units and the hypotenuse is 31.

Thus, we have;

sin \ x=\frac{23}{31}

Dividing, we get;

sin \ x=0.74

Taking sin ^{-1} on both sides of the equation, we get;

x=sin^{-1}(0.74)

x=47.7

Rounding off to the nearest whole integer, we get;

x=48

Thus, the value of x is 48°

Hence, Option c is the correct answer.

The perimeter of the triangle
Illusion [34]
Area=228 feet sqa.
Length=12 ft.
Breadth=(228/12) ft.
=19 ft.
Perimeter=2(12+19) ft.
=2×31 ft.
=62 ft.

The triangle below is isosceles (two congruent sides). Find the value for x. one side say x + 3.8 and the other says 16 and then
Ugo [173]
The <span>isosceles triangle has two congruent sides

Their lengths are (</span> x + 3.8 ) and  <span>16

Equate them :

x+3.8=16


Solve for x:
3=16-3.8=12.2
