The answer is A
***********************************
A is independent while b is dependent.
This is because b is equal to a decreased by 2. Anytime a changes, then b does as well. B can only change in accordance with a.
Ok
in a 30-60-90 right triangle, if the leg oposite the 30 degree angle is x then the hypontuse is 2x
if the leg oposite the 30 degree angle is 12 inches then the hypontuse is 12*2 or 24 inches
Answer:
D
Step-by-step explanation:
A P E X
Cos(x)= adjacent/hypotenuse
cos(18)=x/25 (cross multiply)
25*cos(18)=x
x= 23.78 cm <--- this is rounded to the nearest hundredth.
