cos θ = $\frac{adjacent}{hypotenuse}$

cos ∠N = $\frac{10}{20.4}$

∠N = cos⁻¹ $(\frac{10}{20.4})$

∠N = 60.65°

Answer: 61°

Solve the following equation for y.

labwork [276]

Answer:

Step-by-step explanation:

2y+2=36

Let's solve this equation for 2y first. This means get 2y by itself.

So to get 2y by itself I need to undo that addition of 2 next to it.

The inverse operation of addition is subtraction.

I'm going to subtract 2 on both sides:

2y =36-2

2y =34

Now we want to get y by itself so we divide both sides by 2 since division and multiplication are inverse operations:

y= 34/2

y= 17

14(0.89)^x+4.5 =162

lisabon 2012 [21]

$14(0.89)^{x + 4.5} = 162$
$\frac{14(0.89)^{x + 4.5}}{14} = \frac{162}{14}$
$0.89^{x + 4.5} = 11\frac{4}{7}$
$ln(0.89^{x + 4.5}) = ln(11\frac{4}{7})$
$(x + 4.5)ln(0.89) = ln(11\frac{4}{7})$
$\frac{(x + 4.5)ln(0.89)}{ln(0.89)} = \frac{ln(11\frac{4}{7})}{ln(0.89)}$
$x + 4.5 = -2101.14032500$
$x = 2105.64032500$
