Question

What is the length of BC in the right triangle below?

Answer 1

Option A

Explanation:

Use the Pythagoras Theorem

Hypotaneous² = base² + height²

BC² = AB² + AC²

BC = √ (AB² + AC²)

BC = √ (12² + 16²)

BC = 20

Answer 2

20

Explanation:

Here's your solution

=> in a right angle traingle

BC^2 = AB^2 + AC^2

=> BC^2 = 16^2 + 12^2

=> BC ^2 = 256 + 144

=> BC^2 = 400

=> BC = √400

=> BC = 20
