In the figure to the right, AB = 7.5 m, BC = 2.5 m, and DE = 1.25 m. Find the perimeter of the figure if all angles are right.

Citrus2011 [14]

So look at it as a normal rectangle with just four sides. AB is 7.5, which is one side. And now to get the other side just add BC and DE together to complete the side. It would be 2.5 + 1.25= 3.75. And to get the perimeter just add 3.75+3.75+7.5+7.5. I hope this makes sense.

Select all of the expressions that are undefined. csc(0) sec(0) csc(pi/2) sec(pi/2) csc(pi) sec(pi)

Softa [21]

Answer:

The answer is "undefined, 1, undefined, undefined, and -1".

Step-by-step explanation:

Finding expression:

$i) \csc(0) = \ cosec 0^{\circ} \\\\= \frac{1}{sin 0^{\circ}}\\\\= \frac{1}{0} \ \\\\$ undefined

$ii) \csc (\frac{\pi}{2})\\\\= cosec \frac{\pi}{2}\\\\= cosec \ 90^{\circ}\\\\= \frac{1}{\sin \ 90^{\circ}}\\\\= \frac{1}{1} \\\\=1\\$

$iii) \sec \frac{\pi}{2} \\\\= sec \ 90^{\circ}\\\\= \frac{1}{\cos 90^{\circ}}\\\\= \frac{1}{0} \\$ undefined

$iv) \csc(pi)\\\\= \ cosec (180^{\circ})\\\\= \frac{1}{\sin 180^{\circ}}\\\\= \frac{1}{0}\\$ undefined

$v) sec (\pi) \\\\=\frac{1}{\cos 180^{\circ}}\\\\= \frac{1}{-1}\\\\= -1$
