Question

Solve for a side in right triangles

Answer 1

AC ≈ 2.18

Explanation:

Using the tangent ratio in the right triangle

tan70° =
`(opposite)/(adjacent)` =
`(BC)/(AC)` =
`(6)/(AC)`

Multiply both sides by AC

AC × tan70° = 6 ( divide both sides by tan70° )

AC =
`(6)/(tan70)` ≈ 2.18 ( to the nearest hundredth )
