Which pairs of polygons are similar? select each correct answer.

Rectangle and first two triangle are similar.

Step-by-step explanation:

Given : Figures with different polygons .

To find  : Which pairs of polygons are similar.

Solution : We have given that different polynomial of different size and shape,

Similar polygons are two polygons with the same shape, but not the same size.

We can see from the given figures two triangles and two rectangle have same shape but not the same size .

But, other figures are quadrilateral and right triangle are not have same shape  and size .

Therefore, Rectangle and first two triangle are similar.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
