Since triangle ABC is rectangular, and its leg AC lies opposite angle 30, its length will be equal to half the length of the hypotenuse BC.
AC = BC / 2 = 6/2 = 3 cm.
The area of a right-angled triangle is half the product of the lengths of its legs.
Savs = AB * AC / 2 = 5 * 3/2 = 7.5 cm2.
Answer: The area of the triangle is 7.5 cm2.
