WebAnswer (1 of 2): Ans : b-a/ab put equation of cot(A+B), cot(A+B) = (cotA cotB - 1)/(cot B + cotA) now here given that, tan A + tan B=a….(1) rewrite equation (1) in ... Web20 May 2024 · Tan (A+B)= [tan (A)+tan (B)]/ [1-tan (A)*tan (B)] also cot (A+B)=1/ [cot (A+B)] but sin (A)=√10/10=y/r so y=√10 and r=10 to find x we use the Pythagorean theorem: x^2=r^2+y^2 x^2=10^2- (√10)^2 x^2=100-10 x^2=90 x=√90 x=3√10 since: tan (A)=y/x=√10/ (3√10)=1/3 also tan B is 4/3 hence: cot (A+B)=1/ [cot (A+B)] but launceston window suppliers
