Answer:

Look down at explanation

Step-by-step explanation:

First off if it is true in inches you could use a ruler to measure the bottom it works if you are desperate a lot of the time. Also the bottom of the trapezoid is 6 meters. If you didn't know the perimeter you could split the trapezoid into a rectangle and a triangle. You just have to take off the irrelevant sides when you put it together. So you take the 2 meters from the top of the trapezoid and then the bottom of the triangle is 4, so just split up the trapezoid and find the perimeter of the triangle and rectangle.

there is a rectangle abcd.the length of the rectangle is increased by 10%.the width of the rectangle is increased by 5%,what is

lesya [120]

Answer:

Therefore the area of rectangle is increased by 15.5%.

Step-by-step explanation:

Assume the length and width of the rectangle be x and y respectively.

The area of the rectangle is = length×width

=xy.

Now the length of the rectangle is increased by 10%.

Then the length of the rectangle increased = $x\times \frac{10}{100}$ .

New length of the rectangle is $=x+\frac{10x}{100}$

$=\frac{100x+10x}{100}$

$=\frac{110x}{100}$

The width of the rectangle is increased by 5%.

Then the width of the rectangle increased = $y\times \frac{5}{100}$ .

New length of the rectangle is $=y+\frac{5y}{100}$

$=\frac{100y+5y}{100}$

$=\frac{105y}{100}$

New area of the rectangle is = $\frac{110x}{100}\times\frac{105y}{100}$

= 1.155 xy.

The percentage of area increase is

$=\frac{\textrm{New area - Original area}}{\textrm{Original area}}\times 100$

$=\frac{1.155xy-xy}{xy}\times 100$

$=\frac{0.155xy}{xy}\times 100$

=15.5.

Therefore the area of rectangle is increased by 15.5%.

Are these triangles similar, if so how do I prove it(SSS,AA or SAS)?

spin [16.1K]

Answer:

There isn't a way to prove that the triangles are similar.

Explanation:

Two triangles are similar if they have the same interior angles and the corresponding sides are proportional.

So, to prove that the triangles are similar we can use:

SSS: The three corresponding sides are proportional

SAS: Two sides are proportional and the angle between them is equal

AA: Two angles have the same measure.

In this case, the yellow angles are equal because they are vertically opposite. They are formed by two lines that intersect.

On the other hand, the side with length 3.6 is corresponding with the side with length 9 but the side with length 4.8 is not corresponding with the side with length 12.

Then, there isn't a way to prove that the triangles are similar.
