A non-negative number is a number which is either zero or a positive number
For numerical example , to satisfy rule
substitute a = 16, m = 2 and k = 2
The square root of a number is the number that we need to multiply by itself to get the original number
Now substituting, a = 16, m = 2 and k = 2 in given rule
![\sqrt[2]{16^{2} } =(\sqrt[2]{16} )^{2} \\\\\sqrt[2]{16*16}=\sqrt[2]{16}* \sqrt[2]{16}\\\\16=16](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B16%5E%7B2%7D%20%7D%20%3D%28%5Csqrt%5B2%5D%7B16%7D%20%29%5E%7B2%7D%20%5C%5C%5C%5C%5Csqrt%5B2%5D%7B16%2A16%7D%3D%5Csqrt%5B2%5D%7B16%7D%2A%20%20%5Csqrt%5B2%5D%7B16%7D%5C%5C%5C%5C16%3D16)
So,

Answer:
h = 4.5 inches
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2) h
We know A b1 and b2
20.25 = 1/2 (5+4)*h
20.25 = 9/2 h
Multiply each side by 2/9 to isolate h
2/9 * 20.25 = 2/9 *9/2 h
4.5 =h
Sin A= 90* C, angle of A and C are suplementary
