Question

Find the area of right angled triangle if the radius of its circumcircle is 7.5 cm and the altitude drawn to the hypotenuse is 6 cm long why the hypotenuse is taken as base in the formula ???

Answer 1

Step-by-step explanation:

 

== diameter of its circumcircle 

=(2×7.5)cm=15cm=(2×7.5)cm=15cm 

Let BD⊥ACBD⊥AC. Then BD=6cmBD=6cm 

1. ∴ar(ΔABC)=(1/2AC×BD)=(1/2×15×6)=45cm^2
