1. You should draw a diagram with the information given in the problem. As you can see in the figure attached, there are two triangles, so, you can calculate the height of the lamp post as below:
 
 h1/b1=h2/b2
 
 h1 is the height asked.
 b1=360 cm+ 90 cm
 b1=450 cm
 h2=160 cm
 b2=90 cm
 
 2. When you substitute these values into  h1/b1=h2/b2, you obtain:
 
 h1/450 cm=160 cm/90 cm
 
 3. Now, you must clear the height "h1". Then, you have:
 
 h1=(160 cm)(450 cm)/90 cm
 h1=72000 cm²/90 cm
 h1=800 cm

find a parametric representation of the solution set of the linear equation. (enter your answer as a comma-separated list of equ
Ostrovityanka [42]

To represent the solution set of a linear equation parametrically, we introduce other parameters like s and t for the free variables.

Every linear equation has n - 1 free variables where n is the number of variables.

For x + y + z = 2, we have 3 variables and 3 - 1 = 2 free variables.

First, let y and z be the free variables, we first solve the linear equation for x to get:

x = 2 - y - z

Therefore , the parametric representation of the solution set is given by :

x = 2 - s -t

y = s

z = t
