Can someone help
me with question C a and b? Please provide an explanation if
you can I’m really stuck

Step-by-step explanation:

It ain't that hard. Let's take the first one:

y = 4x + 2z

If you wanna make x the subject, you try to get rid of anything by its side. In other words:

Everything boils down to 2 easy steps:

Now let's check the second example:

That's it :)

If you have any questions please feal free to ask

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

what does muffins have to do with anything?
