Answer: 1145 ft
Step-by-step explanation:
tan 45=1145/x
x tan45/1=1145
x tan 45/ tan 45= 1145/ tan 45
x= 1145/ tan45= 1145... ≈1145
I dont know if this is right but from my background knowledge you can tell that a fraction corresponds with a repeating decimal because it’s repeating the same numbers over and over and a terminating decimal would end.
16z^2-25=0
(4z)^2-(5)^2=0
This is in the form of a^2-b^2=(a+b)(a-b)
(4z)^2-(5)^2=(4z+5)((4z-5)
Answer:
-10
