Question

What is the length of the unknown side? Hint: Pythagorean Theorem.

Answer 1

Answer:

5

Step-by-step explanation:

The Pythagorean theorem is: a^2 + b^2 = c^2

The hypotenuse (the diagonal line) is c, while the base and side are a and b.

4^2 + 3^2 = c^2

16 + 9 = c^2

25 = c^2

the square root of 25 is 5, so c would be 5

Answer 2

Answer: 5

Step-by-step explanation:

Pythagorean Theorem:  a² + b² = c²

Side A: 4

Side B: 3

Side C/ Hypotenuse: ?

1) Form equation...

4² + 3² = c²

2) Simplify and Solve...

16 + 9 = c²

c² = 25

3) Now find the square root of 25 which is c (your answer)

$\sqrt{25} = 5$
