Hey there!
Okay, so when you get a problem like this, all you need to do in insert the given value into the function and solve.
For example:
As you can see, they state that <em>(a) = 27, </em>so you insert 27 in for a in the function and it will look like this:
h(27) = 3(27) + 5
Now you solve on the right side of the equal sign:
3(27) = 81 (you multiply them)
81 + 5 = 86
When you plug the value of 27 in for a in this function, your output is equal to 86.
This is actually quiet easy!
(23.80/140) x 100 = (0.17) x 100 = 17%
That's how you do it! Hope this helps!

Hope it helps
Add the two angles and set them equal to 180, them solve for x
