  1. PQ = X1 = 15 m.
    X2 = hor. distance from Q to kite.

    Tan45 = h/X2
    h = X2*Tan45

    Tan35 = h/(X1+X2)
    h = (X1+X2)*Tan35 = (15+X2)*Tan35

    X2*Tan45 = (15+X2)*Tan35
    X2 = 10.5 + 0.7X2
    0.3X2 = 10.5
    X2 = 35 m.

    h = X2*Tan45 = 35 * Tan45 = 35 m.
    h = (X1+X2)*Tan35 = 50*Tan35 = 35 m.
