10=2/3n+8<br>what is n ?​
alexira [117]

The value of n in the given equation is -2.6

Step-by-step explanation:

Given,

10 = \frac{2}{3n+8}

To find the value of n

10 = \frac{2}{3n+8}

or, 10(3n+8) = 2 [ by cross multiplication]

or, 30n + 80 = 2

or, 30n = 2-80 [ taking the constant values in one side]

or, 30n = -78

or, n = \frac{-78}{30}

or, n = -2.6

If the sin 90° = 1, then the cos 0° = _____. (1 point)
Cloud [144]
<span>sin 90° = 1
</span>
cos 0° = 1

There's a simple formula : <em>sin θ = cos (90°- θ)</em> or <em>cos θ = sin (90°- θ) </em>

So : cos 0° = sin (90° - 0°) = sin 90° = 1
