Answer: C. x = 6; m∠XOY = 18

Step-by-step:

We see that ZOW and WOX are supplementary, meaning the sum of their angles equal 180.

We also know that WOY is a right angle and equals 90.

Now we can solve

180-108 = 72

90 - 72 = 18

XOY = 18

Because 3x = 18, we know that x = 18 by dividing 18 by 3

15 POINTS: The ratio of the same side interior angles of two parallel lines is 33:3. Find the measures of all eight angles forme

larisa [96]

Answer:

$15^\circ,165^\circ,15^\circ,165^\circ\\15^\circ,165^\circ,15^\circ,165^\circ$

Step-by-step explanation:

The ratio of the same side interior angles of two parallel lines is 33:3

If two parallel lines are cut by a transversal

Sum of the same side interior angles = 180 degrees.

Therefore, the two same-side interior angles are:

$\dfrac{33}{36}\times 180^\circ =165^\circ\\\dfrac{3}{36}\times 180^\circ =15^\circ$

We can then say that the measure of all eight angles formed by the parallel lines and transversal starting from the upper left in a clockwise rotation is:

$15^\circ,165^\circ,15^\circ,165^\circ, 15^\circ,165^\circ,15^\circ,165^\circ$

HELP!! I'm not sure what goes in the blank.

natta225 [31]

Answer:

10 $sin^{2} ($ β $)$

Step-by-step explanation:

We can find this two ways, first by seeing in the step after it, cosines are canceled out. Since you already have 10 $sin^{2} ($ β $)$ on the next step, you can assume that (since only the cosines changed and the cosine next ot the blank was removed), the value is 10 $sin^{2} ($ β $)$ .

You can also use double angle formulas from the previous step:

(sin(2β) = 2 sin(β) cos(β))and find that:

5 sin (2β) sin(β) = 5 * (2 sin(β) cos(β)) sin(β)) = (10 sin(β) sin(β)) cos(β) =

10 $sin^{2} ($ β $)$ cos(β)

But since cos(β) is already present, we can see that the answer is 10 $sin^{2} ($ β $)$

a tea company surveyed shoppers at two different malls. shoppers were asked whether they prefer sweetened or unsweetened tea. at

FromTheMoon [43]

First, let's create the ratios of sweetened to unsweetened. To do this, you would have to subtract the number of people that preferred unsweetened from the total.
Westside mall: 15:30 or $\frac{15}{30}$
Eastside mall: 13:26 or $\frac{13}{26}$

Now, you would divide to both ratios.
15 ÷ 30 = 0.5
13 ÷ 26 = 0.5

They have the same sum, meaning, they are the same.

Westside Mall shoppers are just as likely to prefer unsweetened tea as Eastside Mall shoppers.

I hope this helps!
