The answer will be 60 degrees because of the angle your trying to fin
Answer:
Step-by-step explanation:
Squaring both sides of the equation would give 
which then simplifies to 
We can then subtract 7 from both sides to get 
Then we can subtract x from both sides, which cancel out and we get 
Then we need to divide both sides by -2 to get 
Then we need to square both sides 
to get rid of the square root to get 9 = x + 6
Then finally subtracting 6 from both sides we get 3 = x
Point slope form: y-y-coordinate=slope(x-x-coordinate)
slope intercept form: y=mx+b
standard form: x + y=
Answer:
n = -7,6
Step-by-step explanation:
n(n+1)+3=45
distributive property: a(b+c) = ab+ac
n²+n+3 = 45
n²+n -42 = 0
factor now
(n+7)(n-6) = 0
n = -7,6
Answer: { x | 5 < x ≤ 100 } OR { x ∈ ℝ | 5 < x ≤ 100 }
Step-by-step explanation:
{ x | 5 < x ≤ 100 }
This means:
"The set of all x's, such that x is greater than 5 and less than or equal to 100"
Another acceptable way to write this is
{ x ∈ ℝ | 5 < x ≤ 100 }
"x ∈ ℝ" simply means x is an element of all real numbers
