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
Answer:
26
Step-by-step explanation:
Use the Pythagorean Theorem: 
Simplify it to 6v=12
divied 12 by 6
v=2
The Associative Property allows you to "regroup" addition and multiplication problems. You can group this problem in two other ways,
(8 + 4) + 3 and (8 + 3) + 4.
Answer:
2/5
Step-by-step explanation:
3/5 / 2/3
3/5 ÷ 2/3
Convert ÷ sign into multiplication, that will turn 2/3 into 3/2
3/5 X 2/3
Divide by 3
3/5 by 3
1/5
2/3 by 3
2/1
1/5 X 2/1
2/5
