<u>Given</u>:
Given that the figure of similar triangles.
The altitude of the triangle is x.
The length of the left part is 30.
The length of the right part is 15.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the geometric mean theorem.
Thus, we have;

Substituting the values, we have;

Cross multiplying, we get;


Taking square root on both sides, we have;

Thus, the value of x is 15√2

so



∵ 
Therefore, the solution is:

Answer:
3
Step-by-step explanation:
as a person who answers in the mathematics session
i will tell you that the answer is 3
12/36 = x/100
Then cross multiply
1200 = 36x
Divide by 36
x = 33.33
Can’t sell 0.33 of an appliance, so your answer is 33.
