Answer:

x = 32°

Step-by-step explanation:

First, find the measure of the obtuse angle that constitutes the straight line.

180 - 72 = 108°

(3x + 12)° and 108° are corresponding angles.

Corresponding angles are angles that form when a transverse line cuts across two straight lines. They are in the same position or corner of the line, making them equal to each other.

(3x + 12)° = 108°

3x + 12 - 12 = 108 - 12

3x = 96

x = 32°

Hope that helps.

5/6k+2/3=4/3 <br> What is K? <br> I don't understand how to do these

Drupady [299]

First, subtract 2/3 from both sides and you get $\frac{5}{6} k = \frac{2}{3}$
Then multiply both sides by 6/5 and you get $k = \frac{4}{5}$

The current Powerball jackpot is estimated to be $193 million. The Powerball lottery is decided every Wednesday and Saturday nig

Answer:

"2.660503478" would be the right answers to the key statement.

Step-by-step explanation:

Drawing 5 balls out of 69 can be done in ( $\frac{69}{5}$ )

= $\frac{69\times 68\times 67\times 66\times 65}{5!}$

Drawing 1 ball out of 26 red balls can be done in ( $\frac{26}{1}$ )

= $26$

Then the chance of drawing 5 out of 69 balls including 1 out of 26 red balls and then both matching the jackpot

= $\frac{1}{11238513\times 26}$

= $\frac{1}{292201338}$

Since the sum of the jackpot is $193-106 and then one ticket costs $2, the estimated value of buying one ticket again for jackpot is $2.

= $\frac{1}{292201338}\times 193\times 10^6+\frac{292201338-1}{292201338}\times 2$

= $2.660503478$
