Answer:
Step-by-step explanation:
Suppose that the side length is s. Imagine that one side is level. Draw a vertical line through the top vertex perpendicular to the base (level side). Label this vertical line "h." Then h and s are related as follows:
√3 h
sin 60 degrees = ------- = --------
2 s
s√3
and so h = the height of the triangle = -----------
2
The area of this triangle is (1/2)(base)(height), which here is:
(1/2)(s/2)( s√3 /2), or
(s^2)√3
A = ---------------
8
I have no idea good question though 69=y
Answer:
The answer is G. y=2x-2
Step-by-step explanation:
y+6=2(x+2)
First you multiply 2 by what is in the parenthesis
y+6=2x+4
Next you get y by itself by subtracting 6
y=2x+4-6
Simplify
y=2x-2
Answer:
i know the answer it is the second one dude if i am wrong sorry
Step-by-step explanation:
Since the y coordinate is the same for both points we only need to know the change in the x coordinates to find the distance between these two points.
5--12=17
So these two points are 17 units apart.
