Question

If 13 Cos A =5 then find Tan A.​

Answer 1

Answer:

given 13cosA=5

• cosA=5/13
• we know cos = adj / hyp
• adj=5,hyp=13
• by Pythagoras theorem :hyp square=side square+ side square
• 13^2=5^2+opposite side^2
• 169=25+opposite side^2
• 169-25=opposite side^3
• 144=opposite side square
• √144=opposite side
• 12=opposite side

tan A=opp/adj

tan A=12/13
