Answer:  The required inverse of the given function is f^{-1}(x)=x+12.

Step-by-step explanation:  We are given to find the inverse of the following function :

f(x)=x-12~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

Let us consider that

f(x)=y~~~\Rightarrow x=f^{-1}y.

So, from equation (i), we get

f(x)=x-12\\\\\Rightarrow y=f^{-1}(y)-12\\\\ \Rightarrow f^{-1}(y)=y+12\\\\\Rightarrow f^{-1}(x)=x+12.

Thus, the required inverse of the given function is f^{-1}(x)=x+12.

The ratio of the angle measures of a triangle is 1:3:5. Find the angle measures. Then classify the triangle by its angle measure
ExtremeBDS [4]
A triangle has 180 degrees.  You can find the total sum of the ratio by adding its parts together 1+3+5 = 9  Now to find out what each part of the ratio is worth we divide the whole value (180) by the sum of the ratio parts (9)
180/9 = 20

Now we multiply each part of the ratio by 20
1 * 20 = 20
3 * 20 = 60
5 * 20 = 100

Since we have an angle greater than 90 degrees this is an obtuse triangle.

The area of the trapezoid is 40 square units.
Whitepunk [10]

Answer:

5 units

Step-by-step explanation:

Image of the trapezoid is attached.

To find the height of the trapezoid (image attached), let's take the formula for area of a trapezoid.

The formula for area of a trapezoid is:

A = (\frac{a + b}{2}) h

Here, a and b represents the bases of the trapezoid.

a = 6

b = 10

h which represents height is unknown.

A = 40

Substitute figures:

40 = (\frac{6 + 10}{2}) h

40 = (\frac{16}{2}) h

40 = 8 * h

Solve for h:

h = \frac{40}{8}

h = 5

The height of the trapezoid is 5 units
