Answer:

$x=5$

Step-by-step explanation:

<u>Similar Triangles</u>

By looking at the construction of the figure, we can safely assume both triangles are similar, i.e. their internal angles are equal and their sides are proportional. Following the proportion of the heights and bases of both triangles we can set this relationship:

$\displaystyle \frac{45}{36}=\frac{5x}{20}$

Simplifying both fractions

$\displaystyle \frac{5}{4}=\frac{x}{4}$

Solving for x

$x=5$

given the line 2x - 3y - 5 = 0, find the slope of a line that is perpendicular to this line. 3/2 2/3 -3/2

svp [43]

2x-3y-5=0
2x-5=3y
3y=2x-5
y= $\frac{2}{3} x- \frac{5}{3}$
Gradient of line 1 = $\frac{2}{3}$
Gradient of line 2;
$m_{1} * m_{2} =-1$
$m_{2} * \frac{2}{3} =-1$
$m_{2} =- \frac{3}{2}$
