Answer:
The volume in cm of the cube is 5 cm.
Step-by-step explanation:
V= l*w*h
Face= l*w <u>or</u> s^2
l= length
w= width
h= height
s= side length
V= volume
F= face value
Every side of a cube is the same length.
Thus, if one side is 5cm long, then the length, height, and width are also 5 cm long.
The side is 5 cm long, because if the face of a cube is 25 square cm then it is the product of the length of one side multiplied by another side (of which they are all the same length).
So the sides have to be equal to 5 cm each to get 25 (when multiplied together).
Answer: 5 cm
120° will be found on in the second quadrant of the unit circle. Specifically, the reference angle will be 60°. This is because the angle measurement starts from the positive x axis, and rotates 120° counter-clockwise. The angle formed at this point between the line and the x-axis (negative direction) is 60°.
The special right triangle formed will have a hypotenuse of 1, and a reference angle of 60°.
We know that the adjacent line, the line opposite the 30° angle, will be 1/2 the hypotenuse, or -1/2. Negative because it goes in the negative x direction.
The opposite end, or vertical side, will be √3/2.
sin(120) = opposite/hypotenuse = √3/2 ÷ 1 = √3/2
cos (120) = adjacent/hypotenuse = (-1/2) / 1 = -1/2
tan (120) = opposite / adjacent = (√3/2) / (-1/2) = -√3
