First, we have to find the length of each side of triangle. Equilateral triangle means 3 sides r in same length, so each side will be 21 ÷ 3 = 7
Now we need to calculate the height of the triangle. We can do this by Pythagoras theorem
Let the height be h
(7/2)^2 + x^2 = 7^2
The area should be 6.0621778265
Or u can say 6.06 corrected to 3 sig fig
Answer: The answer I got is 3 and pls correct me if I'm wrong
Step-by-step explanation: y=2x+2 and (-1,3)
y=2x+2
3=2(-1)+2
3=-2+2
3=0
-0 =0
