Devon says that triangles tuv and xyz are similar because tu/xy uv/yz xz/tv what is wrong with his reasoning?

Devon use instead of in his reason. So, we can say that triangles are not similar.

Step-by-step explanation:

If two triangles are similar then their corresponding sides are proportional.

If triangle TUV and XYZ are similar, then

The reason given be Devon is

He use the correct concept, that the corresponding sides of similar triangle are proportional. But he use instead of in his reason.

Therefore his reason is incorrect. So, we can say that triangles are not similar.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
