Question

ABC is aright angle triangle with the right angle at vertex B. BD is a altitude through B. Given BD=12cm and AD =9 cm .find the length of BC

Answer 1

Answer:

Use pythagorean theorum

Step-by-step explanation:

$bc{} =\sqrt{12^{2} -9^{2} }$ if the length bc is opp to the 90 degree right angle meaning its hypotenuse the the only change is that there will be + in the equation rather than -

if bc is hypotenuse the answer is more than 12 confirmed if it isnt then it can never be more than 12
