If tan θ =(√3)/3, 0◦< θ < 360◦,

1 answer:

3 0

Arctan (√3 /3) = 30°. = π/6 rad

That is the value searched, in degrees and radians.

You can verifiy that tan(30°) = sin(30°) / cos(30°) = [1/2] / [√3/2] = 1/√3 = √3 / 3

Solve for x round to the nearest tenth of degree if necessary

ehidna [41]

Answer:

x = 1 degree

Step-by-step explanation:

Using the Pythagorean theorem, $a^{2} + b^{2} + c^{2}$ we can find the unknown side then use SOHCAHTOA to find the unknown angle

First step:

$a^{2} + b^{2} = c^{2} \\45^{2} + 92^{2} = c^{2} \\2025 + 8464 = c^{2} \\10489 = c^{2} \\$

Take the square root of both sides

$\sqrt{10489} = \sqrt{c^{2} } \\102.4 = c$

Now to find the angle use SOHCAHTOA

Cosine = $\frac{Adjacent}{Hypotenuse}$ (The side we found is adjacent)(Hypotenuse is the longest side)

= $\frac{102.4}{92}$

= 0.999

Approximately 1 degree.

2. Assume f(x) = g(x). Which of the following functions may be used to represent the equation 3x+2 = 7x + 6? A. f(x) = x + 2, g(

charle [14.2K]

Answer:

C. f(x) = 3·x + 2, g(x) = 7·x + 6

Step-by-step explanation:

The given equations relates to the property of equality of values;

The given formula for the association between f(x) and g(x) is f(x) = g(x)

The given equation of two expressions is 3·x + 2 = 7·x + 6

By transitive property of equality, the two above equations are correct when f(x) = 3·x + 2 and g(x) = 7·x + 6

Therefore, the function that may be used to represent the equation is option C; f(x) = 3·x + 2, g(x) = 7·x + 6.
