Answer:

\frac{\sin^2(\theta)}{\cos(\theta)}

Step-by-step explanation:

\sec(\theta)-\frac{1}{\sec(\theta)}

Write first term as a fraction:

\frac{\sec(\theta)}{1}-\frac{1}{\sec(\theta)}

Multiply first fraction by 1=\frac{\sec(\theta)}{\sec(\theta)}:

\frac{\sec^2(\theta)-1}{\sec(\theta)}

Use Pythagoren Identity, \tan^2(\theta)+1=\sec^2(\theta):

\frac{\tan^2(\theta)}{\sec(\theta)}

Rewrite using quotient identity, \frac{\sin(\theta)}{\cos(\theta)}=\tan(\theta), and recirpocal identity, \frac{1}{\cos(\theta)}=\sec(\theta):

\frac{\frac{\sin^2(\theta)}{\cos^2(\theta)}}{\frac{1}{\cos(\theta)}}

A factor of \frac{1}{\cos(\theta)} cancels:

\frac{\sin^2(\theta)}{\cos(\theta)}

What is the sum of the interior angles of an octagon?<br> 720°<br> O 900°<br> 1,080°<br> 1,260°
timofeeve [1]

Answer:

1080

Step-by-step explanation:

All sides are the same length (congruent) and all interior angles are the same size (congruent). 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

The distance between the two islands shown on the map is 210 miles. A ruler measures the distance on the map is three 1/2 inches
BARSIC [14]
<span>210 miles equals 1 and 1/2 inches (3 1/2"s or 0.5"). 1 and 1/2" is equal to two 3/4" (3/4 + 3/4 = 1 and 1/2). 1.5" is equal to 210 miles, and 1.5" is equal to 2 * .75", you can divide 210 miles by two, which gives you 105 miles.</span>
