Answer:
BC ≈ 3.3
Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan A =
, that is
tan20° =
=
( multiply both sides by 9 )
9 × tan20° = BC , then
BC ≈ 3.3 ( to the nearest tenth )

Answer:
Step-by-step explanation:
Step-by-step explanation:


To solve this system of equations, let's first add the equations together:




There are no values of
that will make this equation true, so the lines never intersect, and therefore there are no solutions to this system of equations.
It is AAaaaaaaaaaaaaaaaaaa
