Answer:
1/7
Step-by-step explanation:
tan A = o/a = 6/8
o= opposite side
a= adjacent side
h= hypotanuse
h² = o²+a²
= 6²+8²
= 36+ 64
= 100
h = √100
= 10
sin A = o/h = 6/10
cos A = a/h = 8/10
cos A - sin A / cos A + sin A
= (8/10 - 6/10) / (8/10 + 6/10)
= (2/10) / (14/10)
= 1/7
Hope this would help you.
