The cosine of 30° is √3 / 2.
Since cosine is Adjacent over Hypotenuse, Hypotenuse = (2 / √3) * 9 = 18 / √3.
The cosine of 45° is √2 / 2.
Therefore, X = (2 / √2) * (18 / √3) = 36 / √6 = 18 / √1.5 = C
Answer:
n ≥ -9
Step-by-step explanation:
Let n = the number
8 <em>less than</em> a number means "n – 8", but
8 <em>less</em> a number means "8 – n," so
8 – n ≤ 17 Subtract 8 from each side
-n ≤ 9 Multiply each side by -1
n ≥ -9
<em>Note</em>: When we multiply by a negative number, we must reverse the inequality.
<em>Check:</em>
Try n = -8.
8 – (-8) ≤ 17
8 + 8 ≤ 17
16 ≤ 17
<em>True</em>.
Such as 1/2 ÷ 1/4, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other then we get the answer 2
