Answer:

m∠RST = 20

Step-by-step explanation:

Sine the line SP bisects ∠RST, we know that the two angles that were formed are equal.  Set ∠RSP equal to ∠PST.

∠RSP = ∠PST

3x - 2 = 9x - 26

(3x - 2) + 2 = (9x - 26) + 2

3x = 9x - 24

3x - 9x = (9x - 24) - 9x

-6x = -24

(-6x)/-6 = -24/-6

x = 4

Now that you know the value of x, add ∠RSP and ∠PST.  This will give you m∠RST.

m∠RST = (3x - 2) + (9x - 26)

m∠RST = 3x - 2 + 9x - 26

m∠RST = 12x - 2 - 26

m∠RST = 12x - 28

m∠RST = 12(4) - 28

m∠RST = 48 - 28

m∠RST = 20

wariber [46]

Answer:

45 km^2 (C)

Step-by-step explanation:

Isolate the smaller square -

We only need two side lengths, take 3km and 3km.

3×3 = 9km^2, that's the area of the smaller square.

Isolate the larger square -

Take 6km and the other 6km

6×6 = 36km^2

Add the square's areas together to get the whole area -

36 + 9 = 45km^2

All you need to do to solve these problems is to isolate the shapes and find their area's, and finally add them together.

Solve for x.<br> 9<br> 2x-111<br> X<br> = [?]
VashaNatasha [74]

Answer:

x=94

Step-by-step explanation:

I hope I'm correct. Here's my explanation: x+9 and 2x-111 would equal 180, hence the line (supplementary). So x+9+2x-111=180

x=94

hope this helps.

Determine whether the bolded numerical value is a parameter or a statistic. Explain your reasoning.The average annual salary of
sergey [27]

Answer:  F. Statistic​, because the data set of salaries of 50 employees is a sample.

Step-by-step explanation:

A parameter gives measure of a characteristic for the entire population where as a statistic gives measure of a characteristic for the subset of population (sample).

Given : The average annual salary of 50 of a company's 800 employees is $54,000.

It means the sample size = 50 and the sample mean salary= $54,000.

i.e $54,000 is giving the measure for mean salary for the sampled 50 employees.

It means $54,000 is a statistic .

Hence, the correct answer is option (F).
