A tree is broken by wind, its upper part touches the ground at a point 10 metres from the foot of the tree and makes an angle of \( 45^{\circ} \) with the ground.
\( \mathrm{P} \) The entire length of the tree is
W
(A) \( 15 \mathrm{~m} \)
(B) \( 20 \mathrm{~m} \)
(C) \( 10(1+\sqrt{2}) \mathrm{m} \)
(D) \( 10\left(1+\frac{\sqrt{3}}{2}\right) \mathrm{m} \)
