tan -1(7/6)
tan -1(6/7)

Answer 1

Hello from MrBillDoesMath!

Answer:

tan ^(-1) (6/7), the last expression in the list

Discussion:

In a right triangle,

tan(@) = side opposite angle\side adjacent to angle.

In our triangle, this becomes

tan(@) = LM \ MN = 6/7 =>

@ is the inverse tangent of (6/7)
