Answer:
5 units
Step-by-step explanation:
The horizontal length is 4 units and the vertical length is 3 units
Consider the right triangle formed by the line, horizontal and vertical.
Using Pythagoras' identity with the line as the hypotenuse h , then
h² = 4² + 3² = 16 + 9 = 25 ( take square root of both sides )
h = [tex]\sqrt{25} [/tex] = 5
The line is 5 units in length
