Answer:
The height of the tower is 94 ft
Step-by-step explanation:
In a given right angle triangle we will use <em>''sohcahtoa"</em><em>.</em>
tan (60°) = opp/adj
tan (60°) = x/50
√3 = x/50
x = 50√3
x = 50 × 1.732
x = 86.6
Now, The height of the tower is (x + 7)
86.6 + 7 = 93.6 ≈ 94
Thus, The height of the tower is 94 ft

Answer:
k = 5 and (6,2).
Step-by-step explanation:
Since (1,-1) is a solution of the equation 3x - ky = 8, so the point (1,-1) will satisfy the equation above.
Hence, putting x = 1 and y = -1 in the equation will give left-hand side = right-hand side.
So, 3(1) - k(-1) = 8
⇒ 3 + k = 8
⇒ k = 5 (Answer)
Therefore, the equation of the straight line is 3x - 5y = 8 ....... (1)
Now, putting x = 6 , then from equation (1) we get y = 2
Therefore, (6,2) is also a point on the graph of equation (1). (Answer)
The square root of 16 is 4
