The missing length of the triangle is 35 units.
According to the question,
We have the following information:
We have a figure of triangle where a line is drawn parallel to the base of the triangle.
Now, we know that in this case the ratio of the corresponding sides of the triangle will be equal.
Let's take the missing length to be x units.
So, we have the following expression:
x/28 = 15/12
Using the cross multiplication method:
12x = 28*15
x = 28*15/12
Dividing by 12 on both sides of the equation:
x = 35 units
Hence, the missing length of the triangle is 35 units.

Step-by-step explanation:
<h3 /><h3>D)X=-4, -2</h3>
is the answer
Decay every two years over a period of t years:
Fourth option: f(t)=(0.75)^(t/2)
decay 2 times a year over a period of t years:
Second option: f(t)=(0.9306)^(2t)
Sixth option: f(t)=(0.8660)^(2t)
decay once per year over a period of t years:
First option: f(t)=(0.9306)^t
Third option: f(t)=(0.8660)^t
