Answer:

x=5 because if y=6 and x=2 the you subtract 2 from 6 and that's 4 so if you subtract 4 from 9 that will give you your answers of 5

Given the pair of triangles are similar find the unknown length of the sides labeled with a variable

MArishka [77]

Answer:

The answer is below

Step-by-step explanation:

The question is not complete. Let us assume the following:

Let us assume triangle ABC is a right angled triangle with side AB = 24, AC = 32 and the hypotenuse BC = 40. Triangle PQR is a right angled triangle similar to triangle ABC with side PQ = 27, PR= b and the hypotenuse QR = a.

Answer:

Two triangles are said to be similar if they have proportional angles or proportional sides that is they have the same shape. For similar triangles, the ratio of their corresponding side are the same.

Given that triangle ABC is similar to triangle PQR, therefore:

$\frac{AB}{AC}=\frac{PQ}{PR}\\ Substituting:\\\frac{24}{32}=\frac{27}{b}\\cross\ multiplying:\\b=\frac{27*32}{24}\\ b=36$

$\frac{AB}{BC}=\frac{PQ}{QR}\\ Substituting:\\\frac{24}{40}=\frac{27}{a}\\cross\ multiplying:\\a=\frac{27*40}{24}\\ a=45$

Which of the following statements is never true?

Serjik [45]

A.
Never true. The angles of an equilateral triangle are 60° each, so an equilateral triangle can never be a right triangle which has one angle 90°.

b.
Possible. An isosceles right triangle has angles 45°, 45°, 90°.

c.
Possible. The angles of an equilateral triangle are 60° each, so it's always an acute triangle.

d.
Possible. For example a triangle with angles 70°, 70°, 40° - the angles are less than 90°, so they are all acute, and there are two angles with the same measure, so it's an isosceles triangle.

The answer is A.
