The sides of a right angle triangle in ascending order of magnitude are 8cm, (x-2)cm and x cm. Find x
A
16
B
17
C
34
D
90
correct option: b
\(8^2 + (x - 2)^2 = x^2\
64 + x^2 - 4x + 4 = x^{2}\
x^2 - 4x + 68 = x^2\
-4x = -68\
-x = \frac{-68}{4} = 17\)
64 + x^2 - 4x + 4 = x^{2}\
x^2 - 4x + 68 = x^2\
-4x = -68\
-x = \frac{-68}{4} = 17\)
