B is the correct answer. hope this helped:)
107.75mThis 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.

plus in values, we know.

switch tan(10) and x using the products property.

plug in to calulator to get answer
x=107.75
i guess is by multiplying 3by the first equation and multiply 2by the second equation

Divide 12 by 3 and you'll get 4.
That means 1/4 or a quarter of the 12 is 3.
(Convert the fraction to its percentage form)
1/4 or 1 divided by 4 equals 0.25
Multiply 0.25 by 100 and you'll get 25%
148.5 square yards of floor covering will be needed to cover the floor.
Step-by-step explanation:
Width of floor = 4 feet 6 inches
Length of floor = 8 feet 3 inches
As we know,
1 foot = 12 inches
Therefore,
Width of floor = 4(12) + 6 = 54 inches
Length of floor = 8(12) + 3 = 99 inches
Area of floor = Length * Width

36 Inch = 1 yard
1 inch = 
5346 inches = 
148.5 square yards of floor covering will be needed to cover the floor.
