The angles of a triangle must add to 180. We know 2 of the angles, so by subtracting them both from 180 we can find the remaining angle.

180 - 75 - 40 = 65

The 65 degree angle and the angle we are looking for are supplementary angles. This means they add to 180.

180 - 65 = 115

The answer is 115.

-22 = 6x + 4<br> Hehehhe I need help agaaaaiiin
UkoKoshka [18]

Hey there!

Answer:\boxed{x=\frac{-13}{3}}

Explanation:

-22=6x+4

Let's start off with flipping the equation.

6x+4=-22

Now we need to subtract 4 from both sides of the equation.

6x+4-4=-22-4\\6x=-26

Now in our third/last step, we will divide both sides by 6.

\frac{6x}{6}=\frac{-26}{6}

x=\frac{-13}{3}

\boxed{x=\frac{-13}{3}}\text{ is the answer.}

Hope this helps!

miss Akunina [59]

Answer:

By an online search, i found that the options are:

Option A. A(10)

Option B. A(11)-A(9)

Option C. A(10)/10

Option D. A’(10)

Let´s start by defining the concept of a derivative.

When we have a function f(x), the derivative, f´(x), is a measure of the rate of change of f(x) with respect to the variable x.

Then if A(t) represents the area covered by the oil, A´(t) is the rate of change of this area as a function of t.

Particularly, A´(10), will be the rate of change at t = 10.

Then the correct option is: Option D. A´(10)
