Question
In a triangle ABC, let ∠C =
If r is the inradius and R is the circumradius of the the triangle ABC, then 2 (r + R) equals
If r is the inradius and R is the circumradius of the the triangle ABC, then 2 (r + R) equalsOptions
A.b + c
B.a + b
C.a + b + c
D.c + a
Solution
2r + 2R = c +
= a + b ( since c2 = a2 + b2).
= a + b ( since c2 = a2 + b2).Create a free account to view solution
