The Area of Shaded region is equal to the difference in Area of rectangle and Area of triangle .

let's solve for area of rectangle :

$➢ \: \: length \times width$

$\longrightarrow8 \times 3x$

$\longrightarrow24x$

Now, Area of Triangle :

$➢ \: \dfrac{1}{2} \times base \times height$

$\longrightarrow \dfrac{1}{2} \times 4 \times x$

$\longrightarrow2x$

So, the area of the shaded region in terms of x :

$\longrightarrow24x - 2x$

$\longrightarrow22x$

And since, Area of Shaded region = 44 cm²

By equating the area, we get

$\large \boxed{ \boxed{22x = 44}}$

Value of x = 2

On a number line, point D is at -6, and point E is at 8. Point F lies between points D and E. If DF: FEis 3: 1, where does point

Vadim26 [7]

F is located on the numbe<u>r 4.5</u><u> </u>on the number line.

<h3></h3><h3>Where does point F lie on the number line?</h3>

We know that point D is at -6

Point E is at 8.

Point F is between D and E, such that the ratio:

DF:FE is 3:1

So if we divide the distance between D and E in 4 parts, 3 of these parts are DF, and one of these parts is FE.

First, the distance between E and D is:

distance = 8 - (-6) = 14 units.

Now, if we divide that by 4, we get:

14/4 = 3.5

Then we have:

DF = 3*(3.5) = 10.5

This means that F is at 10.5 units to the right of D, then:

F = D + 10.5 = -6 + 10.5 = 4.5

F is located on the numbe<u>r 4.5</u><u> </u>on the number line.

Can I make a right angle by drawing an acute angle and and an obtuse angle that share a common ray?

Trava [24]

Yes you could because the obtuse angle is greater than 90 degrees so if the acute angle is inside the obtuse you could get an right angle or an 90 degree angle
