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


BD =

Answer 1

Answer:

BD = 8.8

Step-by-step 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

Answer 2

Step-by-step explanation:

$\sin \: 27 \degree = \frac{CD}{BD} \\ \\ \therefore \: 0.4539 = \frac{4}{BD} \\ \\ \therefore \: BD = \frac{4}{0.4539} \\ \\ \therefore \: BD = \frac{40000}{4539} \\ \\ \therefore \: BD =8.81251377 \\\\ \huge \orange {\boxed {\therefore \: BD \approx \: 8.8}}$
