a = ?
b = 16
c = 20
c2-b2=a2
To find the value of 'a', we need to solve the equation c^2 - b^2 = a^2.
Given that b = 16 and c = 20, we can substitute these values into the equation:
20^2 - 16^2 = a^2
400 - 256 = a^2
144 = a^2
√144 = √a^2
12 = a
Therefore, the value of 'a' is 12.
To find the value of 'a', we can use the given equation:
c^2 - b^2 = a^2
Let's substitute the values:
a^2 = c^2 - b^2
a^2 = 20^2 - 16^2
First, calculate the squares of 20 and 16:
a^2 = 400 - 256
Next, perform the subtraction:
a^2 = 144
To find the value of 'a', we need to take the square root of both sides of the equation:
√(a^2) = √144
Taking the square root of 144, we get:
a = ±12
Therefore, the value of 'a' can be either +12 or -12.
To find the value of `a` using the equation `c^2 - b^2 = a^2`, follow these steps:
Step 1: Substitute the given values into the equation.
c^2 - b^2 = a^2
(20)^2 - (16)^2 = a^2
Step 2: Solve the equation.
400 - 256 = a^2
144 = a^2
Step 3: Take the square root of both sides to find the value of `a`.
√144 = √a^2
12 = a
Therefore, the value of `a` is 12.
