Question

Find the measure of side b

Answer 1

b ≈ 43 yd

Explanation:

Using the tangent ratio in the right triangle

tan28° =
`(opposite)/(adjacent)` =
`(BC)/(AC)` =
`(23)/(b)` ( multiply both sides by b )

b × tan28° = 23 ( divide both sides by tan28° )

b =
`(23)/(tan28)` ≈ 43 yd ( to the nearest whole number )
