The sum of sides of a triangular park is 534 m, and the ratio of sides is 3 : 4 : 5, then find the area of park?

In a cicles with centre O two tringles ABC and BCD are drawn from same chord BC, A and D points are on the circumference of the circle. E is the point of intersection of AC and BD. If ∠A = 40⁰ and ∆ABC is an isosceles triangle where AB = AC and BD is the angle bisector of ∠B, then find the value of ∠BCD?

In ∆ABC, ∠B = 90⁰ and AC = 30 cm, if the median BD is drawn on hypotenuse, then find the length of median?

The ratio of perimeter of two similar triangle ABC and QPR respectively is 45 : 29. If the length of AB, BC and CA is 15 cm, 18 cm and 12 cm respectively, then find the value of side PQ?

In ∆ABC, AB = BC = 25 cm and AC = 34 cm. If BD is the perpendicular bisector on AC, then

Find the value BD?

If ABCD is the cyclic quadrilateral and external of ∠C = 43⁰, then find the value of opposite interior angle?

The interior angle bisectors of ∠B and ∠C in ∆ABC meet at point P. If ∠A = 40⁰, then find the value of ∠BPC?

In ∆ ABC, ∠ A = 30⁰ and AB = 19 cm, AC = 16 cm, then find the area (in cm²) of triangle ABC?
