Answer:
Probabibilt-observation of probality/Total outcomes
=1/7
Answer:
x=17
Step-by-step explanation:
The Pythagorean theorem
a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse
8^2 + (x-2)^2 = x^2
64 + (x-2)(x-2) = x^2
FOIL
64 + x^2 -2x-2x+4 = x^2
Combine like terms
68+x^2 -4x = x^2
Subtract x^2 from each side
68+x^2-x^2 -4x = x^2-x^2
68 -4x = 0
Add 4x to each side
68-4x+4x= 4x
68 = 4x
Divide by 4
68/4 = 4x/4
17 = x
Answer:
x = distance from the building = 837 ft
y = height = -483 ft (The building is DOWN from the plane.)
θ = angle of depression = to be determined
tan θ = y/x
tan θ = -0.577060932
θ = arctan (-0.577060932)
θ = -29.98756509 ° ≈ -30 ° (The building is DOWN from the plane.)
