Question

tan a + tan b = 1 and tan a -tan b =1/7 find tan a and tan b please gyus appropriate answer .....!​

Answer 1

Answer:

hence, tan a = 4/7 and tan b = 3/7

Step-by-step explanation:

tan a + tan b = 1 ---(i) and tan a - tan b = 1/7 ----(ii)

adding (i) & (ii) :

therefore, 2*tan a = 8/7

tan a = 4/7

so, from (i) : 4/7 + tan b = 1

tan b = 1-4/7

so, tan b = 3/7
