Answer:

BE = 7.8

Step-by-step explanation:

$\frac{13}{5}$ = $\frac{x}{3}$

cross multiply

5x = 13 * 3

5x = 39

x = 39/5

x = 7.8

2x + 4 1/5 = 9
2x = 9 - 4 1/5
2x = 5 1/5
2x divided by 2 = x
5 1/5 divided by 2 = 13/5 (2 3/5, or 2.6)
x = 13/5 (2 3/5, or 2.6)

What is the value of n? A. 59 B. 95 C. 23 D. 36

Advocard [28]

Answer:

B. 95 degrees

Step-by-step explanation:

So in this situation we have to find out the value of the angles in the triangle.

To start off we know that 121 is the value of the top outside angle, right.

And the line it is sitting on is flat.

So the angle on the other side should be able to add up with 121 and make 180 degrees.

So 180 minis 121 is 59 degrees.

Now for the other angle, let’s do 144.

So we know that the inside angle has to add up with the outside to make 180 so 180 minus 144 is 36.

Now we know that all the angles inside a triangle should add up it be 180.

So when adding 36 and 59 degrees we get 95.

So the inside angle in the left side has to add with 95 to be 180.

So 180 minus 95 is 85 degrees.

Now that we know the inside angle we have to find out the outside angle.

So we know that 85 has to add up with the outside angle to be 180.

So we do 180 minus 85 which gets us 95 degrees.

The perimeter of a quadrilateral (four-sides polygon) is 50 inches. The longest side is three times as long as the shortest side

kkurt [141]

The side lengths of quadrilateral are 21 inches; 11 inches; 11 inches; 7 inches.

SOLUTION:

Given, the perimeter of a quadrilateral (four-side polygon) is 50 inches.

Let the length of shortest side be n inches. The longest side is three times as long as the shortest side.

That is, length of largest side = 3n inches

The other two sides are equally long and are 4 inches longer than the shortest side.

Then, length of remaining two sides = 4 + n inches

We have to find the length of all four sides.

Now, we know that, perimeter = 50 inches

$\begin{array}{l}{\rightarrow \text { Sum of all sides }=50} \\\\ {\rightarrow n+3 n+n+4+n+4=50} \\\\ {\rightarrow n+3 n+n+n=50-4-4} \\\\ {\rightarrow 6 n=42} \\\\ {\rightarrow n=7}\end{array}$

So, length of sides will be,

$7 \text { inches; } 3\times7=21 \text { inches; } 7+4=11 \text { inches; } 7+4=11 \text { inches. }$

Can someone please help

Kitty [74]

Answer:

ez, all you need to do is find the area of the rectangle by itself so 3x9 is 27, cuz its formula is bxh then u need to find the area of the triangle so 3x3 which is 9 and divde by 2 which is 4.5 and 27-4.5 is 22.5 so thats ur answer.
