Viren trigonometri

Har en oppgave jeg sliter med her, noen som tør prøve seg? Svaret er 18,96m,
Tow guys wires stretch from the top T of a vertical pole to points B and C on the ground, where C is 10m closer to the base of the pole, than B is. If wire BT makes an angle of 35 degrees with the horizontal, and wire CT makes an angle of 50 degrees with the horizontal, how high is the pole?
