Use Pythagorean Theorem
c2 = a2 + b2
152 = a2 + 12 
a2 = 152 - 122 
 =225 - 144 = 81
a = 9 ft
Distance from base of antenna = 9ft

Answer:
t = 21d
Step-by-step explanation:
Here tension and distance are denoted t by d  and  respectively. Since  t varies directly with d , then the relation between  t and d is k=td Given that, for the tension 42 pounds, the spring is stretched 2 inches. Substituting  t = 42 and d= 2 into  t = kd find the value of k . Therefore,
42= K (2)

K= 21
Thus the relationship is t = 21d
