Question

सोबतच्या आकृतीत, जरAC =12 सेमी.तरAB व BC काढा.​

Answer 1

Answer:

AB=6root3cm , BC=6cm

Step-by-step explanation:

$cos60 = \frac{ 1 }{2} = \frac{bc}{ab} \\ \frac{1}{2} = \frac{bc}{12} \\ 12 = bc \times 2 \\ \frac{12}{2} = bc \\ 6 = bc \\ \\ \\ tan60 = \frac{ab}{bc} \\ \sqrt{3} = \frac{ab}{bc} \\ \sqrt{3} \: = \frac{ab}{6} \\ \sqrt{3} \times 6 = ab \\ 6 \sqrt{3} = ab$
