Using right triangle relations, we will get:

tan(B) = 1.05
sin(B) = 0.735
cos(B) = 0.7

<h3>How to find the value of the trigonometric equations?</h3>

We assume that bot triangles are equivalent, then the angle B will be the same as the angle Z.

Now remember the relations:

tan(θ) = (opposite cathetus)/(adjacent cathetus).
sin(θ) = (opposite cathetus)/(hypotenuse)
cos(θ) = (adjacent cathetus)/(hypotenuse).

If we step on angle B, we have:

opposite cathetus = 29.4
adjacent cathetus = 28
hypotenuse = 40.6

Replacing that, we get:

tan(B) = 29.4/28 = 1.05
sin(B) = 29.4/40.6 = 0.735
cos(B) = 28/40.6 = 0.7

Given: $f(x) = \frac{1}{x-2}$

$g(x) = \frac{2x+1}{x}$

A.)Consider

$f(g(x))= f(\frac{2x+1}{x} )$

$f(\frac{2x+1}{x} )=\frac{1}{(\frac{2x+1}{x})-2}$

$f(\frac{2x+1}{x} )=\frac{1}{\frac{2x+1-2x}{x}}$

$f(\frac{2x+1}{x} )=\frac{x}{1}$

$f(\frac{2x+1}{x} )=1$

Also,

$g(f(x))= g(\frac{1}{x-2} )$

$g(\frac{1}{x-2} )= \frac{2(\frac{1}{x-2}) +1 }{\frac{1}{x-2}}$

$g(\frac{1}{x-2} )= \frac{\frac{2+x-2}{x-2} }{\frac{1}{x-2}}$

$g(\frac{1}{x-2} )= \frac{x }{1}$

$g(\frac{1}{x-2} )= x$

Since, $f(g(x))=g(f(x))=x$

Therefore, both functions are inverses of each other.

For the Composition function $f(g(x)) = f(\frac{2x+1}{x} )=x$

Since, the function $f(g(x))$ is not defined for $x=0$ .

Therefore, the domain is $(-\infty,0)\cup(0,\infty)$

For the Composition function $g(f(x)) =g(\frac{1}{x-2} )=x$

Since, the function $g(f(x))$ is not defined for $x=2$ .

Therefore, the domain is $(-\infty,2)\cup(2,\infty)$

The angle between the minute hand and the hour hand of a clock is 90 degrees. What time is it? Justify your answer.

tangare [24]

If it is exactly 90 degrees you are looking for, your answer would be, 3:0:0. Which is 3:00.

27 over X =3 and 5y = 35 what is the value of <br> X• Y?

diamong [38]

Answer:

Step-by-step explanation:

$\frac{27}{x} = 3$

divide, 27 ÷ 3

you'll get 9, so

x = 9

Next part

5y = 35

divide both sides by 5 to isolate y,

5y ÷ 5 = 35 ÷ 5

y = 7

x = 9 and y = 7

Then let's add the numbers to our equation ( x × y)

9 × 7
