Let a triangle ABC with BC = 6 cm, and the area of 30 cm2. A square PQRS is inscribed so that points S and R is on BC, Q on AC, and P on AB respectively. Find the side length of the square PQRS.
+1694 ΔABC is an isosceles triangle.
Angles B and C are congruent. Their tangent = 10/3 = 31/3
2(x / 31/3 ) + x = 6
Square side x = 3.75 cm
