Hope this helps you. I apologize if it’s incorrect.
From the identity,
sin^2(x)+cos^2(x)=1
then
cos(x)=sqrt(1-sin^2(x))
where sin(x) is given as 0.42.
Note that the above answer applies to 0<x<90 degrees
Answer: second one (B) - 2.045, 2.43, 259
Step-by-step explanation: 2.045 is the lowest value due to the 0 in the hundredths place. 2.43 has a lower value than 259, it being a decimal.
Answer:
4.92+4z
Step-by-step explanation:
You can always add or subtract
same value to/from both sides of equation. The same is true about multiplication and division.
In your case you have to subtract
x from both sides of equation in order to get rid of it on the left side:


But it's easier to remember that if you want to move some member of equation to other side, you just have to
change it's sign. Let's practice a bit using your equation (I have added "plus" signs where they are usually omitted to better understend what's going on):

Move
2y to the right side:

Move
8 to the left side:

Move both
x and
2y to the right side:
