We know that
the scale factor on the blueprint is-------> 12 cm/20 m------> 3 cm/5 m
if 3cm on a blueprint-------------> represent 5 m in the actual
X cm---------------------------------> 15 m
X=15*3/5------>X=9 cm
the answer is
9 cm
3y - 12 = -6
3y = 6 | Add 12 to both sides
y = 2 | Divide by 3 on both sides
Answer: y = 2 (Answer B)
We develop two different right triangles in which the opposite side to the given angle of depression is 1500 ft and the length of the runway is the y.
(45°) --> tan (45°) = 1500 ft / y₁
y₁ = 1500 ft
(42⁰) --> tan (42⁰) = 1500 ft / y₂
y₂ = 1665.92 ft
Finding the difference between two y's, the answer would be 165.92 ft.
