ΔXYZ was reflected to form ΔLMN.
goldfiish [28.3K]

ΔXYZ was reflected to form ΔLMN, hence ΔXYZ ≅ ΔLMN, ∠X ≅ ∠L and XZ ≅ LN

<h3>What is transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are <em>rotation, translation, reflection and dilation.</em>

Reflection is a rigid transformation, hence it produces congruent figures with congruent angles.

∠Y + ∠X + ∠Z = 180 (angle in a triangle)

86 + 38 + ∠Z = 180

∠Z = 56°

Also:

∠N + ∠M + ∠L = 180 (angle in a triangle)

86 + 56 + ∠L = 180

∠L = 38°

ΔXYZ was reflected to form ΔLMN, hence ΔXYZ ≅ ΔLMN, ∠X ≅ ∠L and XZ ≅ LN

Bad White [126]

Answer:

s =  \frac{5}{3}

p =  \frac{7}{3}

Step-by-step explanation:

for this equation

a=3

b= -5

c = -7

The sum of equal to

-  \frac{b}{a}

and the product is equal to

\frac{c}{a}

. All you do is replace the values. You can prove both of those using the quadratic formula.
