Hey Dear,
● Answer -
x = 30 m
● Explanation -
[Refer to the figure for better understanding.]
Distance XC is calculated by -
XC = BC.sin45°
XC = 30√2 × 1/√2
XC = 30 m
But,
XC = XO + OC
XC = XO + AB
30 = XO + 20
XO = 10 m
Now, distance x will be calculated as -
x = OA
x = BC.sin45°
x = 30√2 × 1/√2
x = 30 m
Therefore, distance x will be 30 m.
Thanks for asking..
