Find the value of x.

Julli [10]

Answer:

$x=4$

Step-by-step explanation:

The two given triangles, triangle (BDE) and triangle (BAC) share the angle (<B) in common. Moreover, their bases, line (DE), and line (AC) are parallel, this means that through the corresponding angles postulate, angles (<BDE) and (<BAC) are congrunet. Moreover, angles (<BED) and (<BCA) are also congruent. Thus, triangles (BDE) and (BAC) are similar through angle-angle similarity.

The ratio between the corresponding sides of similar triangles is the same. Therefore, one can form the following equation,

$\frac{BD}{BA}=\frac{BE}{BC}$ .

Substitute,

$\frac{BD}{BD+DA}=\frac{BE}{BE+EC}\\\\\frac{x+2}{x+x+2}=\frac{3}{3+2}$

Simplify,

$\frac{x+2}{2x+2}=\frac{3}{5}$

Cross products,

$5(x+2)=3(2x+2)\\$

Simplify, distribute, multiply every term inside the parenthesis by the term outside of it,

$5x+10=6x+6$

Inverse operations,

$5x+10=6x+6\\\\10=x+6\\\\4=x$

Answer:

"How often do you seek medical information online?"

Of 1072 Internet users who chose to respond, 38% of them responded with "frequently."

The respondents here are voluntary response sample and are a self-selected sample.

The thing that is wrong here, it that it is possible that many people read the survey but may choose not to respond and also the few responses will not reflect the opinions of all the population.
