Answer:
long = 8.66
Step-by-step explanation:
pythagorean theorem
short squared + long squared = hypotenuse squared
25 + long squared = 100
long squared = 75
square root of long squared = square root of 75
long = square root of 75
long = 8.66025403784
The area of the square= bxh
= 6x6= 36
The area of the rhombus is 4/5 the area of the square so 36x 4/5 = 28.8
Area of rhombus = basexheight
28.8= 6x height
Height = 28.8/6
Height =4.8
Rotating 180 degrees about the point p.
If they are perpendicular reflecting across each one will have the same effect as if the point was rotated 180 degrees about the certain point.
