In the given figure △ABC is equilateral. If IE = 4 cm , IB = ____.
8 cm
16 cm
4 cm
10 cm
△ABC is equilateral .........(Given)
In △IBE , ∠IBC=30∘ .........BI bisects (∠ABC)
sin 30∘=rR ...........(sin 30∘=12)
⇒ r : R = IE : IB = 1 : 2
IE = 4 cm
⇒ IB = 8 cm
In the given figure △ABC is equilateral. If IB = 6 cm , then IE = ____.
In the given figure △ABC is equilateral. The ratio IE : IB = ____.
In the figure displayed below, if RQ = 8 cm, find the value of RS.
