I need help on this math problem!

20 inches

Step-by-step explanation:

The problem is having you solve for the hypotenuse of a right triangle so you'll use the pythagorean theorem.

12²+16²=400.

√400= 20

20 inches.

Hope this helps!

20 inches

Explanation:

Imagine the two sides to be the length and width of a triangle, and the line he drew as the hypotenuse. Thus, we can use the Pythagorean theorem:

c² = a² + b²

c² = 12² + 16²

c² = 144 + 256

c² = 400

c = 20 in.

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)

also, thx a lot for the points : )

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
