Miguel made 80 on his Math test. He made 95 in last week's Math test.

We need to find the percent change on his scores. It can be calculated as follows :

So, there is a percent change of 15.78%.

x = 20

Step-by-step explanation:

To do this question, you can use the pythagorean theorem.  c is your hypotenuse, a is the unknown side length and b is the known side length.

a^2+b^2=c^2

x^2+15^2=25^2

x^2=225=625

x^2=400

(x^2)^(1/2)=400^(1/2)

x = 20
