If `A=75^@,B=45^@,` then prove that `b+csqrt(2)=2a`

If A=75^(@),B=45^(@), then prove that b+c sqrt(2)=2a

If A=75^0,b=45^0, then prove that b+csqrt(2)=2a

If A=45^(@) and B=75^(@) , show that a+csqrt(2)=2b .

If A+B=45^(@) then prove that (1+tan A)(1+tan B)=2. On the basis of the result obtained prove that tan22.5^(0)=sqrt(2)-1

If A+B=45^(@) , then prove that (i) (1+ tan A) (1+ tan B) =2 (ii) (cot A-1) (cot B-1)=2

If in a triangle ABC, A=45^(@) , B=75^(@), then the value of (a+sqrt2c) is-

If x+y=45^(@) , then prove that: a) (1+tanx)(1+tany)=2 b) (cotx-1)(coty-1)=2
