Answer:
x = - 3 ± 
Step-by-step explanation:
Given
4x² + 24x = 4 ( divide through by 4 )
x² + 6x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 1 + 9
(x + 3)² = 10 ( take the square root of both sides )
x + 3 = ±
( subtract 3 from both sides )
x = - 3 ± 
Answer:
The tower is about 235 m.
Step-by-step explanation:
Let x be the height of the tower
tan θ = opp / adj
tan 78 °= x / 50
x = 50 tan 78 °
x = 235
∴ The tower is about 235 m.
Hope this answer helps you :)
