This is a trigonometric ratio problem. the angle of depression (10) is opposite the height (19m) and the distance is adjacent to the distance (x). opposite ad adjacent sides to the angle is a tangent problem.
tan \theta = \frac{opp}{adj}
plus in values, we know.
tan (10) = \frac{19}{x}
switch tan(10) and x using the products property.
x = \frac{19}{tan (10)}

Lemur [1.5K]

Answer:

Therefore the maximum number of bouquets is 12.

Step-by-step explanation:

Given that, Angelina has 24 tulip and 36 roses.

To find the number bouquets, we need the find out the g.c.d (greatest common divisor) of 24 and 36.

24= 2×2×2×3

36=2×2×3×3

The common factors are = 2,2,3

The g.c.d of 24 and 36 is =2×2×3

                                         = 12

Therefore the maximum number of bouquets is 12.
