Two observers P and Q 15m apart observe a kite in the same vertical plane and from the same side of the kite.The angle of elevation of the kite from P and Q are 35 degree and 45 degree respectively.Find the height of the kite to the nearest metre.

Answer 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.
