Answer:
The third side is 3
Step-by-step explanation:
The given triangle is a right-angled triangle. Pythagoras theorem can be used to find the third side of the triangle.
Pythagoras theorem states that:
[tex](Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2[/tex]
Given
Base = 4
Hypotenuse = 5
Putting the values in the formula
[tex](5)^2 = (4)^2 + (Perpendicular)^2\\25 = 16 + (Perpendicular)^2\\25-16 = (Perpendicular)^2\\(Perpendicular)^2 = 9[/tex]
Taking square root on both sides
[tex]\sqrt{(Perpendicular)^2} = \sqrt{9}\\Perpendicular = 3[/tex]
The third side is 3
