Question

find the value of c and yz if y is between x and z. xy = 5.5, yz = 2c, xz = 8.9

Explanation:

Step1: Aplicar la propiedad de segmentos

Como $Y$ está entre $X$ y $Z$, entonces $XY + YZ=XZ$.
$5.5 + 2c=8.9$

Step2: Resolver para $c$

Restar 5.5 de ambos lados de la ecuación:
$2c=8.9 - 5.5$
$2c = 3.4$
Dividir ambos lados por 2:
$c=\frac{3.4}{2}=1.7$

Step3: Encontrar el valor de $YZ$

Sustituir $c = 1.7$ en $YZ = 2c$.
$YZ=2\times1.7 = 3.4$

Answer:

$c = 1.7$; $YZ = 3.4$
