It would be obtuse.

It's neither, because it's according to Pythagoras Theorem, s+2nds<l

How do I do this I'm am really confused?

Since (4y-42) and 2y are opposite angles, they equal to each other which looks like this:

4y-42 = 2y

From there you want to put the y onto one side:

4y-2y-42=0 -----> 2y-42=0

You want to balance the equation out and move the -42 onto the other side so you add it to both sides to get:

2y=42

Then divide both sides by 2 to get:

y= 21

From there you can plug 21 back into the original equation to find each angle.

4(21)-42 = 2(21) ---> 84-42 = 42 ---> 42 = 42

So y = 21 and each angle is 42 degrees

Answer:

Mathematics uses numbers and data to find ways to describe relationships, importance, value, dependency/independency of variables, and many other things. These computations and concepts are essential to the world because of our human need to make comparisons and place value on things.

Answer:

$\frac{5\pm\sqrt{73}}{4}$

Step-by-step explanation:

The quadratic formula:

$\frac{-b+\sqrt{b^2-4ac}}{2a}$

So, we need to move all the terms to one side of the equation, which now becomes

$2x^2-5x-6=0$

Plugging in the numbers and you'll get the two roots/

QuestionIn PQR, sin P = 1/3, sin R = 2/3,and p = 9. Find the side length r.

mamaluj [8]

Lets draw our triangle:

Lets use the "Law of Sines" to find our side r:

$\frac{p}{\sin P}=\frac{r}{\sin R}\rightarrow\frac{9}{\frac{1}{3}}=\frac{r}{\frac{2}{3}}\rightarrow9\times\frac{3}{1}\times\frac{2}{3}=r\rightarrow r=18$

So r=18

A random sample of n = 4 scores is obtained from a normal population with m = 30 and s = 8. what is the probability that the sam

tangare [24]

the probability that the sample mean will be smaller than m = 22 is 0.02275.

For the given question,

A z-score measures exactly how many standard deviations a data point is above or below the mean. It allows us to calculate the probability of a score occurring within our normal distribution and enables us to compare two scores that are from different normal distributions.

Here sample size, n = 4

mean, μ = 30

standard deviation, σ = 8

The probability that the sample mean will be smaller than m = 22 is

z = $\frac{m-\mu}{\frac{\sigma}{\sqrt{n} } }$
