Question

in a rectangular triangle ABC A=90° AB=4 and AC=3. Find the BC hypotenuse using pythagorean theorem.​

Answer 1

BC=5

Explanation:

BC^2= AB^2 + AC^2

x^2= 4^2 + 3^2

x^2= 16 +9

x^2= 25

x=

`{ √(25) }`

x= 5

Answer 2

BC² = AB² + AC²

BC = √(4² + 3²)

BC = √(16 + 9)

BC = √25

BC = √5²

BC = 5
