The answer is 75
First you subtract 180 and 165 to find that smallest angle inside the triangle(15). Then you add 15 and 90,the two angles you know, and do 180 - 105= 75.
The trick is that all angles inside a triangle equal 180 degrees. Hope this helps!
-3x<9. The way to figure this out is to divide by -3 to get x by itself. Remember, when dividing by a negative, you need to flip the inequality sign.
x>-3 is your answer.
I hope this helps!
Volume of the cube is given as 512 cm^3
We also know that
Volume of a cube = (side)^3
Then we can use this formula to find the size of each side of the cube very easily.
Let us assume the length of each side = x
Then
x^3 = 512
= 8
So the length of each side of the cube is 8 cm. I hope you have got the answer you were looking for. You can crosscheck the answer by multiplying 8 three times. You will get the result as 512. This is the only method to solve this problem.
