Answer:
<h2>
![\cos(A) = \frac{2 \sqrt{6} }{7}](https://tex.z-dn.net/?f=%20%5Ccos%28A%29%20%20%3D%20%20%5Cfrac%7B2%20%5Csqrt%7B6%7D%20%7D%7B7%7D%20)
</h2>
Step-by-step explanation:
Since we are finding cos A we have
<h3>
![\cos(A) = \frac{AC}{AB}](https://tex.z-dn.net/?f=%20%5Ccos%28A%29%20%20%3D%20%20%5Cfrac%7BAC%7D%7BAB%7D%20)
</h3>
From the question
AC = √96
AB = 14
Substitute the values into the above formula
That's
<h3>
![\cos(A) = \frac{ \sqrt{96} }{14}](https://tex.z-dn.net/?f=%20%5Ccos%28A%29%20%20%3D%20%20%5Cfrac%7B%20%5Csqrt%7B96%7D%20%7D%7B14%7D%20)
</h3>
We have the final answer as
<h3>
![\cos(A) = \frac{2 \sqrt{6} }{7}](https://tex.z-dn.net/?f=%20%5Ccos%28A%29%20%20%3D%20%20%5Cfrac%7B2%20%5Csqrt%7B6%7D%20%7D%7B7%7D%20)
</h3>

False, Complementary angles equal to 180 degrees and Supplementary angles equal to 360 degrees
N=-55 -n=11x5 -n= 55 n=-55
(multiply both sides by -1)
3x+ 8= x-4
2x + 8= -4
2x= -12
x= -6
