Question

What is the length of the line?

Answer 1

5 units

Explanation:

By the Pythagorean theorem:

c² = a² + b²

c = length of the line

a = 4

b = 3

Then:

c² = 4² + 3²

c² = 16 + 9

c² = 25

√c² = √25

c = 5

Answer 2

5 units

Explanation:

Use Pythagorean Theorem

x = 4 units y = 3 units

4^2 + 3^2 = L^2

16 + 9 = L^2

L = 5
