In a triangle, the sum of lengths of two sides is x and the product of the lengths of the same two sides is y. If x 2 – c 2 = y, where c is the length of the third side of the triangle, then the circumradius of the triangle is
A
B
y
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Sol. Let a, b, c be the three sides, given
a + b = x, ab = y , (a + b) 2 – c 2 = ab
here 
= – 
⇒ 
= 2R ⇒ 
= 2R ⇒ R =
