2D Coordinate - find the length of perpendicular foot on tilted system












0














enter image description here
I am given values of $x_1, y_1, x_2, y_2$, $theta_{1}$, and $theta_{2}$.



I want to find out the value of the Unknown height.



The Unknown height is length of the perpendicular feet between Point 2 and the line extending towards the upper right side of the page.



How can I find the length of the perpendicular feet?

          Calculate the distance between points $P_1$ and $P_2$:



          $$
          d_{12} = [(x_2 - x_1)^2 + (y_2 - y_1)^2]^{1/2}
          $$



          and note that



          $$
          sin theta_1 = frac{mbox{unknown height}}{d_{12}}
          $$



          So that



          $$
          mbox{unknown height} = d_{12} sin theta_1
          $$
