An aircraft (at Z) is spotted by two observers (at X and Y) who are L = 1950 feet
1 answer:
Answer:
889.70 feets
Step-by-step explanation:
From the solution diagram attached :
C = 180 - (40 + 45) = 95°
According to the sine rule :
Sin95 / 1950 = Sin40 / b = Sin 45 / a
1950 sin40 / sin 95 = b = 1248.22 ft
1950 sin 45 / sin 95 = a = 1384.13 ft
Sin 40 = h / 1384.13
h = 1384.13 * sin 40
h = 889.70 feets

Here, RUMH and RUBM are two rhombus as shown in the diagram.
As, a rhombus has four equal sides,
so for RUMH, side RH = side HM = side MU = side UR
and for RUBM, side RM = side MB = side BU = side UR
As HM=UR and MB= UR , so we can write HM = MB
Now for two triangles ΔRHM and ΔUMB,
side RH = side MU
side RM = side BU
and side HM = side MB
'Side Side Side' theorem states that if three sides of one triangle are equal to three sides of another triangle respectively, then the two triangles are similar.
That means, ΔRHM = ΔUMB
