if △stu ~ △xyz, which statements must be true? check all that apply.

startfraction s t over x y endfraction = startfraction t u over y z endfraction
startfraction x y over s t endfraction = startfraction su over x z endfraction
∠s ≅ ∠x
∠t ≅ ∠y
st = xy
su = xz

Step-by-step explanation:

Given:

So, from the similarity we deduct that three pair of angles are congruent: ∠S ≅ ∠X, ∠T ≅ ∠Y and ∠U ≅ ∠Z.

Similarly, sides are proportional, this means that corresponding sides are in the same relation:

We ignore the reasons why this triangles are similar, but once they are similar we can deduct all.

Therefore, the correct answers are:

ST/XY = TU/YZ

∠S ≅ ∠X

∠T ≅ ∠Y

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
