Answer
Find out the altitude of the equilateral triangle .
To proof
By using the trignometric identity.

As shown in the diagram
and putting the values of the angles , base and perpendicular


solving


As

put in the above
a = 4 × 3
a = 12 units
The length of the altitude of the equilateral triangle is 12 units .
Option (F) is correct .
Hence proved
A. incenter
point w is shown in the triangle formed by 3 different lines. these lines are called angle bisectors, and the point at which the angle bisectors meet is called the incenter of a triangle
Answer:
Correct choice is B
Step-by-step explanation:
The exponential regression model can be written as exponential function

Then

Thus,

When
you get
