Answer 2

Answer:

height = 900√3

Step-by-step explanation:

speed between A and B

= 648 km/hr

= 648×1000/3600 m/sec

= 180 m/sec

time taken from A to B = 10 sec

distance between A and B= AB = speed × time

= 180×10 m= 1800 m

In triangle AOD, AD= OD ×tan 60= OD √3

In triangle OBC, BC= OC × tan 30= OC/√3

height = AD = BC

OD√3 = OC/√3

OC=3×OD

OD + CD= 3×OD

2×OD=CD=AB=1800m

OD= 900 m

AD= OD ×√3= 900×√3 m
