If the angles<br> are represented in degrees, find both angles:<br> sin(x + 7) = cos(4x + 8)
ValentinkaMS [17]

Answer:

x = -1/3

Step-by-step explanation:

We have,

sin(x + 7) = cos(4x + 8)

We need to find the value of x.

We know that,

sin(90-x) = cosx

So,

sin(90-(x + 7)) = cos(4x + 8)

cos(x+7) = cos(4x + 8)

i.e.

(X+7) = (4x+8)

7-8 = 4x-x

-1 = 3x

x = -1/3

12y 2 y 2 +15y+26 ​ ÷ y 2 −9y 3y 3 +39y 2 ​ =start fraction, y, squared, plus, 15, y, plus, 26, divided by, 12, y, squared, end
Luda [366]

The equation is not typed properly, and it is difficult to understand. But it is clear that you are trying to determine the value of y that makes your equation undefined.

An fraction is undefined if it's denominator is zero, that is if it's of the form a/0.

The value that makes a fraction undefined is the value that makes the denominator vanish. The value that makes its denominator equal to zero.

Example:

1. (x - 3)/(y - 5) is undefined if

y - 5 = 0

Or y = 5

2. (3x² + 4xy + 6)/(x + 2)(y + 6)

If x + 2 = 0, or y + 6 = 0

That is if x = -2, or y = -6

You can use this idea to find the value of y that makes your equation undefined.

When x = 2e, <img src="https://tex.z-dn.net/?f=%5Clim_%7Bh%20%5Cto%200%7D%20%5Cfrac%7Bln%28x%20%2B%20h%29%20-%20ln%28x%29%7D%7Bh
dybincka [34]

Supposing you know about the derivative, notice that

\displaystyle\lim_{h\to0}\frac{\ln(x+h)-\ln x}h=\dfrac{\mathrm d(\ln x)}{\mathrm dx}=\dfrac1x

so that when x=2e, the limit is equal to \dfrac1{2e} and the answer is A.
