To find the value of c, 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 (a and b).
Using the formula:
c^2 = a^2 + b^2
Plugging in the values:
c^2 = 21^2 + 28^2
Simplifying:
c^2 = 441 + 784
c^2 = 1225
Taking the square root of both sides:
c = √1225
Simplifying:
c = 35
Therefore, the value of c is 35.
To find the value of 'c' in the equation A^2 + B^2 = C^2, where A = 21 and B = 28, we can substitute the given values into the equation.
Using the given values, the equation becomes:
21^2 + 28^2 = C^2
Simplifying the equation, we have:
441 + 784 = C^2
1225 = C^2
To find the value of C, we take the square root of both sides of the equation:
√1225 = √C^2
35 = C
Therefore, the value of 'c' is 35.
To find the value of `c` in the equation A² + B² = C², where A = 21 and B = 28, we can substitute the given values into the equation:
(21)² + (28)² = C²
Now, let's calculate:
441 + 784 = C²
1225 = C²
To find the value of `C`, we need to take the square root of both sides:
√1225 = √C²
35 = C
Therefore, the value of `c` is 35.
