Answer:
C) (square root 2)/2
Step-by-step explanation:
In quadrant III, the sine of an angle is positive. The value will be ...
sin(Θ) = √(1 -cos(x)^2) = √(1 -(-√2/2)^2) = √(2/4)
sin(Θ) = (√2)/2
Answer:
62.8
In a triangle the sum of interior angles is always 180 degree. So by appropriate equation we get the result as
angle C = 90 -27.2=62.8
Answer:
Step-by-step explanation: h = -2t + 25
2t = the distance the glider will pass descending with constant speed of 2 m/s (distance = speed*time)
25 = the initial height that will decrease by the distance that the glider will pass while descending during time t
Answer:
The answer is 21.3
Step-by-step explanation:
Answer:
7/20
Step-by-step explanation:
10 blue marbles, 4 black marbles, 5 white marbles, and 6 red marbles = 25 marbles
25-10 = 15
There are 15 not blue marbles
P( not blue ) = not blue marbles / total = 15/25 = 3/5
keep the not blue marble
25-1 = 24 marbles left
15-1 = 14 not blue marbles
P( not blue ) = not blue marbles / total = 14/24 = 7/12
P( not blue, keep, not blue) = 3/5 * 7/12 = 21/60 = 7/20
