Hi there!
The answer would be 120 so D.
Add all the measurements: 20 + 60 + 40 and you get 120.
Hope this helps ;)
Answer:
the answer for number 38 is H
The length of side BD is; 13.
<h3>Length measure in a triangle</h3>
From the given diagram;
- It follows that the ratio which holds is;
12 : x = 27 : x + 5
12/x = 27/x+5
27x = 12x +60
- subtract 12x from both sides
15x = 60
x = 4.
On this note, the length of the line BD is;
= BC + CD
= 4 + (4 + 5)
= 4 + (9)
= 13
Therefore, the length of the line BD is 13.

When it is said that a variable is inversely proportional to another, it is best to write out an equation to represent it.
This means;
y=k/x (where k is a constant number like 1 or 2, etc)
If you double x, the value of y is halved. I have attached a graph that shows this.
Hope I helped :)
