Question

PLEASE HELP ASAP!!! I NEED CORRECT ANSWERS ONLY PLEASE!!!

Find BD.


Write your answer as an integer or as a decimal rounded to the nearest tenth.


BD =

Answer 1

Explanation:

`\sin \: 27 \degree = (CD)/(BD) \\ \\ \therefore \: 0.4539 = (4)/(BD) \\ \\ \therefore \: BD = (4)/(0.4539) \\ \\ \therefore \: BD = (40000)/(4539) \\ \\ \therefore \: BD =8.81251377 \\\\ \huge \orange {\boxed {\therefore \: BD \approx \: 8.8}}`

Answer 2

BD = 8.8

Explanation:

You have a right triangle.

The hypotenuse is BD

The side opposite the 27o angle is 4

Sin(27) = opposite / hypotenuse.

Sin(27) = 0.45399

opposite = 4

hypotenuse = ?

0.45399 = 4/hypotenuse

BD = 4/0.45399

BD = 8.811

The answer is 8.8
