Step-by-step explanation:
- x+x+x=65
- 3x=65
- x=65/3
- x=21.67
When we're finding the mean we add all the numbers then we DIVIDE THE AMOUNT OF NUMBERS. In this case, we have to divide by 5 because that's the amount of numbers there are.
Answer:
4 questions
Step-by-step explanation:
50 divided by 12.5 is 4
Multiply all the numbers by what you see on the screen and the six the side and then divide it into a equal amount.
<span>x=theta
so we know that tanx = sinx/cosx
therefore is tanx = 4/3 and sinx = -4/5
we can set up an equation to find cosx
so 4/3 = (-4/5)/cosx
we can multiply x to have cosx(4/3)=-4/5
we can then divide 4/3 over so we have
cosx = (-4/5)/(4/3)
therefore, cos x = -3/5

there is the answer
i hope this help
