Answer:
C
Step-by-step explanation:
Since the triangle is right with hypotenuse QR
Use Pythagoras' identity to solve for QR
The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is
QR² = 8² + (8 )²
= 64 + 192
= 256 ( take the square root of both sides )
QR = = 16
Using a graphical tool we obtain that the solution of this system
(intersection between the lines)
is given by the point (x,y) = (2,4)
(intersection between the lines)
is given by the point (x,y) = (2,4)
