a rectangle is 16m by 9cm find a side of the square whose area equals the area of the rectqngle by how much does the perimeter of the rectangle exceed the perimeter of the square
EF is parallel to the tangent at A, point on the circle and Angle ABC= 57 ,Angle ACB = 55, the measure of Angle AFE??
Triangle ABC is circumscribed touching the circle at P,Q,R.if AP= 4 cm, BP= 6 cm, AC = 12 cm, BC= x cm. Then x=?
BoC is a diameter of a circle with centre O. If AB and CD are two chord such that AB parellel to CD. If AB = 10 cm, then CD=?
