Given cos theta is equal to - 4/ 7 then we can conclude that theta is in the second and third quadrants. In this case, the other leg is equal to square root of (7^2 - 4^2 ) equal to square root of 33. In this case, sin theta can be equal to +- square root of 33 / 7 and tan theta is equal to +-square root of 33 / 4.
Answer:
Step-by-step explanation:
We will be able to fill the glass up to the amount of water possible to hold in the glass, minus the amount in the cube. This means it will be able to hold 
cubic cm of water.
Using the difference of cubes formula(you can prove this by expanding back out again), we get that 
Therefore, the answer is 
cubic centimeters and we're done!
Direct variation equal is written as : y = kx
K is the constant of variation.
12 = k4
12/4 = k
k = 3
