The value for n is
<u>given data</u>
10n^{2} - 12 = -8
making n the subject of the formula
10n^{2} = -8 + 12
10n^{2} = 4
divide through by 10
n^{2} = 4 / 10
finding the square root of both sides
n = square root ( 4 / 10 )
n = 0.632 or

Answer:
+120/169 or -120/169
Step-by-step explanation:
where, alpha is some angle that satisfies the assumed condition.
[ taking cos to the other side or applying cos on both sides]
as sin =
[by general trigonometry formula: ]
so if , we can get sin
from the above formula as + or - 12/13
(because, after taking square root on both sides we keep + or -]
[by general trigonometry formula]
so, the final value can be 120/169 or -120/169.
