Question

If cosA
12/13

then find sin A and tan A​

Answer 1

Answer:

sinA =5/13

cosA=5/12

I hope it is helpful

Answer 2

Answer:

if cos A is 12/13 then secA is 13/12

make a triangle naming ABC where AB is 12 and AC is 13

then using pythagoras theorem

AB square + BC square = AC square

putting the values in appropiate place we get BC=5

so sinA =5/13

tanA =5/12
