Easy just add up the steps, if both of them scored 8 and one scored by 4 just add em up.
For this case, what we must do is solve the following system of equations:
tan (50) = h / x
tan (40) = h / (x + 50)
Solving the system we have:
(x + 50) * tan (40) = h
(x) * tan (50) = h
Matching:
(x + 50) * tan (40) = (x) * tan (50)
Rewriting:
x (tan (50) - tan (40)) = 50 * tan (40)
x = 50 * tan (40) / (tan (50) - tan (40))
x = 118.9692621
Substituting:
h = (x) * tan (50)
h = (118.9692621) * tan (50)
h = 141.7820455
Answer:
The height of the building is:
h = 141.7820455 ft
Answer:
Decimal: 0.375 Percent: 37.5%
Step-by-step explanation:
Step-by-step explanation:
-2|5x + 3| >= 4
|5x + 3| <= -2
Since absolute value is never negative, there are no real values for x.
