Question

Solve for a side in right triangles

Answer 1

AC ≈ 4.28

Explanation:

using the tangent ratio in the right triangle

tan35° =
`(opposite)/(adjacent)` =
`(BC)/(AC)` =
`(3)/(AC)` ( multiply both sides by AC )

AC × tan35° = 3 ( divide both sides by tan35° )

AC =
`(3)/(tan35)` ≈ 4.28 ( to the nearest hundredth )
