Answer:
The answer to your question is: Ф = 43.95°
Step-by-step explanation:
Data
length = 18 ft
distance bottom to is 13 ft
x = angle = ?
Formula
cos Ф = opposite side / hypotenuse
Process
cos Ф = 13 ft / 18 ft substitution
cos Ф = 0.72 simplify
Ф = cos⁻¹ (0.72)
Ф = 43.95° result
Which expression has a value that is equivalent to 5n+13 when n=-15? n^2+13x
Answer:
it's the last one on the bottom (the one you chose)
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Multiply both sides by 7.
5s+8=28
Subtract 8 from both sides.
5s=20
Divide 5 from both sides,
s=4
3-2y-8x is it's most simplified form I think.
