If two angles of ABC are 45° and 60°, then the ratio of the smallest and the greatest sides are
In ABC, with usual notation, observe the two statements given below :
Both I and II are true
I is true, II is false
I is false, II is true
Both I and II are false
A.
Both I and II are true
We know that = rr1r2r3
and s2 = r1r2 + r2r3 + r3r1
So, both the statements are true.
If A = 35°, B = 15° and C = 40°, then tan(A) · tan(B) + tan(B) . tan(C) + tan(C) . tan(A) is equal to
