Math will give ! in a 45-45-90 triangle, what is the length of the hypotenuse when the length of one of the legs is 5 in.? √5 in. 5√5 in. 2√5 in. 5√2 in.

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.
