In a Right-angled triangle, one angle is 60°. If hypotenuse measures 12cm, then the sides of the triangle are
6cm,6√2cm,12cm
6cm,6√3cm,12cm
6√2cm,6√3cm,12cm
6√2cm,6√3cm,12√2cm
Construct a right-angled triangle whose hypotenuse measures 5 cm and the length of one whose sides containing the right angle measures 4.5cm.
