Answer:

<h2>135 degrees</h2>

<h2>To find the measure of the angles, we know that the sum of all the angles is 1080 degrees (from above)... And there are eight angles... So, the measure of the interior angle of a regular octagon is 135 degrees.</h2>

Evaluate: sin (225degree)

PtichkaEL [24]

Sin(225)

225 degrees is in the 3rd quadrant. And in the third quadrant only tangent is positive, sin is negative.

For third quadrant, basic angle = 225 - 180 = 45

sin225 = - sin45

sin225 = - sin45 = -0.7071

sin 225° ≈ -0.7071
