You will be using Pythagoras so the setup will be in the image
Answer:
The leghts of AB is 9 because both of the triangles are symmetrical. But also, this is a Equilateral triangle, which means that both of the sides are the same lengths (AB=AC)
591,912 rounded to the nearest thousands = 592,000
If x=4 , then . . .
... 7x = 28
... 7x+4 = 28+4 = 32
... absolute value of 32 is 32.
... -(absolute value of 32) = -32
