Question

Using the formula, solve for c, if a = 9 and b = 40

a² + b2 = c²
A C = 7
B. C = -25
C. c = 41
D. c= /49

Answer 1

The answer is option C

Explanation:

c² = a² + b²

a = 9 , b = 40

Substitute the values of a and b into the equation and solve

That's

`{c}^(2) = {9}^(2) + {40}^(2) \\ {c}^(2) = 81 + 1600 \\ {c}^(2) = 1681 \\ c = √(1681)`

We have the final answer as

c = 41

Hope this helps you
