Answer:
<h2>20</h2>
Step-by-step explanation:
Use the Pyhagorean theorem:

We have the lengths of legs 12 and 16. Substitute:

You do 9/10. Which here it only fits once. So this is 1 1/10. The other one fits 3 times. So its 3 1/10.
If you want the subtraction also done its 1 4/10.
150 can't go into 180 equally, so the answer is 1.2
Answer:

because it says "f(x)" and then it says"Find f(-1)" so that is why I think x = -1
