-4
Step-by-step explanation:
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
Answer:
y = x
Step-by-step explanation:
Slope-intercept form is the form that looks like
... y = mx + b . . . . . . for slope m and y-intercept b
The line connecting points D and E has slope 1 and y-intercept 0, so the equation is ...
... y = 1·x + 0
... y = x . . . . . . without the identity elements
_____
<em>Comment on the marked choice</em>
The choice that is marked is the equation in <em>point-slope form</em> using the point E (4, 4). That is not the form requested by the problem.
