The answer is 0.5778 or 0.578 rounded
Answer:
a:vertex angle
Step-by-step explanation:
it is vertex angle
The answer is zero.
If any of the pairs of lines were parallel, there would be some same-side interior angles or such that would be supplementary. However, since the lines are not parallel lines crossed by a transversal, the only ones guaranteed to be supplementary to angle 7 are the ones adjacent to it that form a linear pair.
The correct answer is: P(even or prime) = 5/6
Explanation:
First the P(E) = Probability of Even = 3/6 = 1/2 (because 2,4,6 are even numbers)
P(p) = Probability of Prime = 3/6 = 1/2 (because 2,3,5 are the prime numbers)
Now
P(even AND prime) = 1/6 (because 2 is not only an even number but also the prime number)
Hence
P(even or prime) = P(E) + P(p) - P(even AND prime) = 1/2+1/2 -1/6 = 5/6
Answer:
(x - 9)(x + 5)
Step-by-step explanation:
x² − 4x − 45 =
= x² + 5x - 9x - 45
= x(x + 5) - 9(x + 5)
= (x - 9)(x + 5)
