Help me plz its math plz help

Hi there! :)

a = 12 units.

Step-by-step explanation:

Using the Pythagorean Theorem (c² = a² + b²), where

c = length of the Hypotenuse

a = length of the shorter leg

b = length of the longer leg

We can calculate the length of "a" by substituting in the values into the equation:

c = 15

a = "x"

b = 9

15² = x² + 9²

Simplify the squares:

225 = x² + 81

225 - 81 = x²

144 = x²

Take the square root of both sides:

√144 = x

x = 12 units.

Therefore, the length of a = 12 units.

a= 12

Step-by-step explanation:

Pythagorean Theorem: a²+b²=c²

b= 9

c= 15

a= x = what we are looking for

For this problem, we need to set c² equal to x² and b², which would look like:

15²= x²+9²

225= x²+81

Subtract 81 from both sides

144=x²

Square root both sides

x=12

a= 12
