Find the value of sin(a/2) if cosa= 12/13<br>

daser333 [38]

Answer: sin $\frac{a}{2}$ = ± $\frac{1}{\sqrt{26} }$

Step-by-step explanation:

We very well know that,

cos2A=1−2sin²A

⟹ sinA = ± $\sqrt{(1-} \frac{cos2A}{2} )$

As required, set A = $\frac{a}{2}$ & cos a= $\frac{12}{13}$ ,thus we get

sin $\frac{a}{2}$ =± $\sqrt{\frac{1-cos a}{2} }$

∴ sin $\frac{a}{2}$ =± $\sqrt{\frac{1-\frac{12}{13} }{2} }$ = ± $\frac{1}{\sqrt{26} }$

since ,360° < $\frac{a}{2}$ <450°

,180° < $\frac{a}{2}$ <225°

Now, we are to select the value with the correct sign. It's is obvious from the above constraints that the angle a/2 lies in the III-quadrant where 'sine' has negative value, thus the required value is negative.

hope it helped!

Find the value of x<br> in this polygon.<br> help !!!

Paladinen [302]

Answer:

solution,

Sum of exterior angle of polygon=360°

$3x - 5 + 2x + 10 + 90 = 360 \\ or \: 3x + 2x - 5 + 10 + 90 = 360 \\ or \: 5x + 5 + 90 = 360 \\ or \: 5x + 95 = 360 \\ or \: 5x = 360 - 95 \\ or \: 5x = 265 \\ or \: x = \frac{265}{5} \\ x = 53$

Hope this helps...

Good luck on your assignment...
