Answer:
y=3x
Step-by-step explanation:
If the part inside the square root is negative, there are imaginary roots. Otherwise they are real.
We know that
in a right triangle
Applying the Pythagoras Theorem
c²=a²+b²
in this problem
c=√87 yd
a=√23 yd
b=?
so
b²=c²-a²-----> b²=(√87)²-(√23)²----> b²=87-23----> b²=64----> b=8 yd
the answer is
8 yd
12 because the rest of the numbers are all similar except 12
