Question

Help.

Answer 1

\[\sin 80 \csc 80\]

Answer 2

Find the exact value.

Answer 3

\(\csc\theta = \dfrac{1}{\sin\theta}\)

Answer 4

okaii i got that..

Answer 5

\[\csc \theta = \frac{ 1 }{ \sin \theta }\]
\[\csc 80 = \frac{ 1 }{ \sin 80 }\]

Answer 6

Ok, what happen if you multiply both sides by sin80?

Answer 7

Then you wold get \(\boxed{\sin 80 \csc 80 = 1}\) right?

Answer 8

BTW i know the answer is 1

Answer 9

Ok.
