A point , (x,y) is reflected across the y axis. the resulting point is (-x,y)
so
if (5.75,0) is the reflected point, then (-5.75,0) is the original
the distance is the double the absolute value of the x value (basically a horizontal line beteen the 2 points)
so
2|-5.75|=2(5.75)=11.5
distance is 11.5 units
Finding x,
We will use Pythagoras theorem to determine the value of x:
Finding y,
We have to determine the angle, at the bottom left of the bigger triangle.
Using sine rule,
To find the angle on the smaller triangle,
Finding the missing length of y,
So y = 2 + 8, y = 10
The sum of three interior angles of any triangle is always 180 degrees.
