Step-by-step explanation:
the right answer!
Karla uses a traditional, manual method of constructing perpendicular lines, using a straightedge while Daryl uses a latest drawing tools to draw them.
Both the methods are correct, however the amount of effort and time taken will vary for these two different methods.
Since Karla is constructing perpendiculars manually so she has to go through all the methods carefully, from placing the straightedge to marking the arcs and joining them correctly. It will take her a little longer and more effort to get the accurate results.
On the contrary, the drawing tool used by Daryl will be much more efficient as he can construct perpendicular lines just by specifying a point in no time.

Step-by-step explanation:
<h2><u>Solution (1) :</u></h2>
Measure of angle ABC = (3x)°
Measure of angle CBD = (15x+18)°
Since angle ABC and angle CBD are a linear pair their sum will be equal to 180°¿
Which means :
Thus, <u>the value of x = 9</u>.
<h2><u>Solution (2)</u> :</h2>
From that equation, we know that the value of x = 9.
Which means :
Measure of angle ABC :
Measure of angle ABC = 27°
Therefore, <u>the measure of angle ABC = 27°</u>
<h2><u>Solution (3)</u> :</h2>
We know that x = 9
Which means :
Measure of angle CBD :
Thus, angle CBD = 153°
Since the measure of angle ABC and angle CBD equals 180°[27+153=180°], we can conclude that we have found out the correct value of each angle.
Therefore, <u>the measure of angle CBD = 153°</u>
