Question

what is the value of c, if a = 5 and b = 8, for the formula? $c = \sqrt{a^2 + b^2}$

Explanation:

Step1: Substitute a=5, b=8

$c = \sqrt{5^2 + 8^2}$

Step2: Calculate squares of a and b

$c = \sqrt{25 + 64}$

Step3: Sum the squared values

$c = \sqrt{89}$

Step4: Compute the square root

$c \approx 9.43$

Answer:

$\sqrt{89}$ (or approximately 9.43)
