Triangles= 180°

Add the 3 angles to equal 180°


17x + (10x - 5) + 50= 180
combine like terms

27x + 45= 180
subtract 45 from both sides

27x= 135
divide both sides by 27

x= 5


ANSWER: x= 5

Hope this helps! :)

Marcy and her sister watched a cartoon movie that was 2 hours and 18 minutes long. after the movie, they played a card game for
Dmitry_Shevchenko [17]

Answer:

1:24pm

Step-by-step explanation:

Couple of ways to solve this. Here is one method
Convert all times to minutes and find the total number of minutes they spent on all 3 activities. Then convert to hours and minutes and subtract from the end time of 5;28 to get the start time of all activities which is also the start time of watching the movie (first activity)

So time spent:

Movie: 2 hours 18 minutes = 2 * 60 + 18 = 120 + 18 = 138 minutes
Card game: 34 minutes
Soccer: 1 hour 12 minutes = 1 * 60 + 12 = 72 minutes

Total time spent = 138 + 34 + 72 = 244 minutes = 4 hours and 04 minutes

Subtract 4:04 from 5:28 to get 1:24pm

Check
Movie watch starts at 4:04, ends at 1:24 + 2:18 or 3:42pm
Card game starts at 3:42pm ends at 3:42+0:34 ==> 4:16pm
Soccer starts at 4:16pm ends at 4:16pm + 1:12 ==> 5;28pm

Given sin(−θ)= −1/4 and tanθ= 15√15 .<br><br> What is the value of cosθ ?
dangina [55]

\sin =  \frac{y}{r}  \\  \\   \tan =  \frac{y}{x}  \\ \\ \cos =  \frac{x}{r} \\  \\   {x}^{2}  +  {y}^{2} =  {r}^{2}

-  \sin =  \frac{ - 1  \: =  \: y}{4  \: =  \: r}
15 \sqrt{15}  =  \frac{1}{x}  \\  \\ x = .017
\cos =  \frac{.017}{4}  = .0043

A picture frame has a perimeter of 62 inches. The difference between the
castortr0y [4]
Answer: each width = 10, each length = 21

Explanation: from the question we know that L=2w + 1 and we also know that a rectangle has the perimeter of 62 when we plug it in the equation we will get 62= 2(2w+1+w) we will multiply the 2 now and we will get 62=4w+2+2w we will combine like terms and we will minus two from both sides ending up with 60=6w we will divide six from both sides and we will get w=10 then we will use l=2w+1 to find the length and it will be 21
