When a diagonal of a square is 24 cm then find out of its perimeter.

In ∆ABC, AD is the internal bisector of ∠A, meeting the side BC at D. If BD = 5 cm, BC = 7.5 cm, then AB : AC is 

In the given figure ABC is an equilateral triangle. Two circles of radius 4 cm and 12 cm are inscribed in the triangle. What is the side (in cm) of an equilateral triangle?

Rectangle ABCD is formed in a circle with centre D. IF AE=6 cm and AD=9 cm, then find the perimeter of the rectangle.

if θ is acute angle and sin (θ+18⁰) = 1/2, then the value of θ in circular measure is :

The length of the chord of a circle is 8 cm and perpendicular distance between center and the chord is 3 cm. Then the radius of the circle is equal to:

Find the value of ∠BAC in the given diagram If AB=AC=CD and ∠ADB=20°?
