Step-by-step explanation:

a. Obtuse Scalene Triangle. It has one angle that is greater than 90 degrees and have two equal sides so it's a obtuse scalene triangle.

b. A triangle interior add up to 180 degrees. We are given the upper angle which is 173. The other two angles must add to 180 but must be equal.

$x + y + z = 180$

$y = z$

$x + z + z = 180$

$x + 2z = 180$

x=173 so

$173 + 2z = 180$

$2z = 7$

$z = 3.5$

3.5 degrees.

If I have 4 eggs and I want to make an omlette, how many more eggs do I need to make an omlette?

lora16 [44]

One omelette will serve one person and, because it is so quick to make, it's not worth cooking a large one for two. So, according to how hungry you are, use 2-3 large eggs per person.

Hope this can help you

Answer:

B, C, F

Step-by-step explanation:

For the first part, this is the negative angle identity of the sine and cosine function. These identities are:

$\cos(-\theta)=\cos(\theta)$

$\sin(-\theta)=-\sin(\theta)$

Then (I believe I am reading this right), B is true. I am unsure because of the repeated value in the middle. The next piece is that sine is odd. By definition, an odd function is one such that:

$f(-x)=-f(x)$

As we just demonstrated with the identities, sine obeys this and therefore is odd. Cosine, on the other hand, is even because it follows:

$f(-x)=f(x)$

Last, the period of sine, or the distance on the x-axis it takes to complete one full wavelength, and the answer is $2\pi$ . If you look at a graph of the sine function, you will find that the wave repeats itself at the $2\pi$ mark and it does this with cosine as well.
