To find the value of c in this right triangle, we can use the Pythagorean theorem which states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the other two sides.
Therefore, c^2 = 20^2 + 21^2
c^2 = 400 + 441
c^2 = 841
c = √841
c = 29
Therefore, the value of c is 29.
The correct answer is B. 29
