Question

tell me the answer of this question​

Answer 1

Step-by-step explanation:

AB² + BC² = CA² (Pythagoras theorem)

(10x - 2)² + (3x - 1)² = (10x)²

(100x² + 4 - 40x) + (9x² + 1 - 6x) = 100x²

100x² + 4 - 40x + 9x² + 1 - 6x = 100x²

109x² + 5 - 46x = 100x²

109x² - 100x² - 46x + 5 = 0

9x² - 46x + 5 = 0

9x² - 45x - x + 5

9x(x - 5) - 1(x - 5)

(9x - 1)(x - 5)

9x - 1 = 0

9x = 1

x = 1/9

x - 5 = 0

x = 5

According to the options 5 is the correct answer.
