Answer 1

Answer:

$\sin( 115 \degree) = 0.906$

Step-by-step explanation:

The general point on a unit circle is given by

$x = \cos( \theta)$

$y = \sin( \theta)$

where

$\theta = 115 \degree$

is the terminal side of the angle in standard position.

Therefore

$x = \cos( 115 \degree)$

$y = \sin(115 \degree)$

lies on this circle

This angle intersects the unit circle at

$( - 0.423,0.906)$

Hence we must have

$\cos( 115 \degree) = - 0.463$

$\sin( 115 \degree) = 0.906$
