The perimeters of two similar triangles are 25 cm and 15 cm respectively. If one side of the first
Vanyuwa [196]

Answer:

5.4cm

Step-by-step explanation:

In similar triangles, the perimeter of the triangles will be in the ratio of their corresponding sides.

The ratio of their perimeter is  

perimeterofΔ2          15

---------------------   = -------------

perimeterofΔ1           25  

So, the side of triangle 2 will be  

  9  *  15                  15

----------------  =   --------------

​  sideofΔ2                25

=  

​⟹side of Δ2=           25  / 9∗15         =5.4.

Is vuw similar to vxy? if yes, explain how you know. if no, explain why not.
Semenov [28]

Answer:

Yes, because m<UVW is congruent to m<XVY and m<VUW is congruent to m<VXY

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

so

In this problem

we know that

m< VUW=55\°

the measure of angle VXY is equal to

m -----> by supplementary angles

m

therefore

m< VUW=m

Remember that

m<UVW=m<XVY -----> is the same vertex

therefore

Triangles VUW and VXY are similar by AAA Similarity Theorem ( the three angles are congruent)
