Answer:
14
Step-by-step explanation:
The answer is C, from where the end lines go down to on the graph
13 = r/9 + 8
subtract 8 from each side
5 = r/9
multiply 9 from each side
r = 45
Answer: 4x^2 + 10x + 25
Step-by-step explanation:
(2x+5)^2 = (2x)^2 + 2(2x * 5) + 5^2
= 4x^2 + 10x + 25
Here, in this situation,
Hypotenuse = 25 feet
base = 13.5 feet
Now, Cos Ф = B / H
Cos Ф = 13.5 / 25
Cos Ф ≈ 1/2
Ф = Cos⁻¹(1/2)
Ф = 45 [ Cos 45 = 1/2 ]
In short, Your Answer would be approximately 45 degrees
Hope this helps!
