The two combinations of two-digit numbers we could have would be 79 and 97. The only one of those that would round to 100 is 97. If we added another digit to the number, it would be over 100. The very smallest three digit number we could have with these two numbers in it would be 179; that would not round to 100. That means 97 must be our number.

Answer:
776.46 m
Step-by-step explanation:
According to the scenario it is a question of right angle triangle
To find the height of the plane above the ground we will use trigonometry identity.
<h3>sinФ = opposite / hypotenuse </h3>
here Ф = 15°
opposite = height
hypotenuse = 3000m
Plug values in the formula above
<h3>sin(15) = height / 3000</h3>
height = sin(15)(3000)
= 776 .46 m
(make sure your calculator is in degree mode)
