Answer:

57.7 m

Step-by-step explanation:

Since the distance between Isabella, the building and the angle form a right angled triangle with the height of the building = h = 50 m as the opposite side and x = distance between Isabella and the building = adjacent side and Ф = angle of elevation of the top of the building from Isabella = 30°.

So, from trigonometric ratios,

tanФ = h/x

and x = h/tanФ

= 50 m/tan30°

= 50/0.5774

= 86.6 m

Also, the distance between Alice, the building and the angle form a right angled triangle with the height of the building = h = 50 m as the opposite side and x' = distance between Alice and the building = adjacent side and Ф' = angle of elevation of the top of the building from Alice = 60°.

So, from trigonometric ratios,

tanФ' = h/x'

and x' = h/tanФ'

= 50 m/tan60°

= 50/1.7321

= 28.87 m

So, the distance between Isabella and Alice, x" = x - x'

= 86.6 m - 28.87 m

= 57.73 m

≅ 57.7 m
