a = 20
b = ?
c = 29
c2-a2=b2
To find the value of b, we can rearrange the equation c^2 - a^2 = b^2 and substitute the given values:
c^2 - a^2 = b^2
29^2 - 20^2 = b^2
841 - 400 = b^2
441 = b^2
Taking the square root of both sides, we get:
b = √441
b = 21
To find the value of b, we can use the equation c^2 - a^2 = b^2, where c is 29 and a is 20.
1. First, substitute the given values into the equation:
c^2 - a^2 = b^2
29^2 - 20^2 = b^2
2. Calculate the squares of the numbers:
841 - 400 = b^2
3. Subtract to find the difference:
841 - 400 = 441 = b^2
4. Take the square root of both sides to solve for b:
√441 = b
b = 21
Therefore, the value of b is 21.
To find the value of b, you can use the equation c^2 - a^2 = b^2, where a = 20 and c = 29.
1. Substitute the values of a and c into the equation:
29^2 - 20^2 = b^2
2. Square the values:
841 - 400 = b^2
3. Perform the subtraction:
441 = b^2
4. Take the square root of both sides to solve for b:
b = √441
5. Calculate the square root:
b = 21
Therefore, the value of b is 21.
