Answer:

<h3><u><em>The value of x = 9.</em></u></h3><h3><u><em></em></u></h3>

Step-by-step explanation:

The figure shown is represented as a right triangle, which means that the sum of the angles within should add up to 90°. So if we take 32° (one of the angles given) and subtract it from 90°, we should be left with 58°.

This means that the value of the equation that contains "x" must equal 58°. Therefore, (6 x 9 + 4)° must equal 58.° Which means that the value of x = 9.

z1/z2

= 3/7 (cos(π/8-π/9) + i sin(π/8 - π/9))

= 3/7 (cos(π/72) + i sin(π/72))

Solve for t: <br> -4(t+4)=-8t-24

kotykmax [81]

Answer:

$\rm{-2$

Step-by-step explanation:

Hi there!

$\rm{-4(t+4)=-8t-24}$

$\rm{-4t-16=-8t-24$

$\rm{-4t+8t=-24+16$

$\rm{4t=-8$

$\rm{-2$

Thus, $-2$ is our final answer.

Hope it helps! Enjoy your day!

Given f(x) = 5x^6 what is the domain?5 < X ≤ 6x ≥ 0X ≤ Oall real numbers

Vilka [71]

The domain is the set of all possible x-values which will make the function "work", and will output real y-values

$\begin{gathered} \text{Let} \\ f(x)=5x^6 \\ \end{gathered}$

there is not a value for x, that makes the function does not "work", so x can take any value, in other words all real numbers

so, the answer is all real numbers

I'm honestly sorry that I'm asking so many questions.<br> Solve for X in the Diagram.

Leno4ka [110]

Answer:

$\Huge\boxed{x=8}$

Step-by-step explanation:

Hello There!

Remember the sum of all of the angles in a triangle is 180

so we can use this equation to solve for x

180 = 50 + 60 + 8x + 6

now we solve for x

step 1 combine like terms

50 + 60 + 6 = 116

now we have

180=8x+116

step 2 subtract 116 from each side

116 - 116 cancels out

180 - 116 = 64

now we have

8x = 64

step 3 divide each side by 8

8x/8=x

64/8=8

we're left with x = 8
