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
3(a+b) and 3a+b: not equivalent
4(x+2y) and 8y+4x: equivalent
Answer:
I got -0.09...
although I could be wrong, don't take my word for it, it's been a while lol
Haha what? Is this like a joke..how does a cat have 18 legs.what that’s confusing
