Question

Please answer correctly !!!!! Will mark Brianliest !!!!!!!!!!!!!!

Answer 1

BC = 205.8 feet

Explanation:

We only have one side, DB, so we have to use the given angles rather than the Pythagorean theorem.

Answer 2

BC ≈ 205.8 ft

Explanation:

Using the cosine ratio in the right triangle

cos71° =
`(adjacent)/(hypotenuse)` =
`(BD)/(BC)` =
`(67)/(BC)` ( multiply both sides by BC )

BC × cos71° = 67 ( divide both sides by cos71° )

BC =
`(67)/(cos71)` ≈ 205.8 ft ( to the nearest tenth )
