In △ABC, right angled at C, AC=4cm and ∠BAC=60∘, find the length of side BC
5√3 cm
3 cm
4√3 cm
√3 cm
Since ∠BAC=60∘ ⇒tan 60∘=BCAC=√3 ⇒BC4=√3 ⇒BC=4√3 cm
In △ABC, right angled at B, BC = 5cm, ∠BAC = 30∘, find the length of the sides AB and AC.
An equilateral triangle ABC is inscribed in a circle of radius 10 cm, which is centered at O, as shown below. Then the length of the side of this triangle is equal to
