Find the value of x. Show your work, congruent triangles

Mathematics
1 answer:
Nataly_w [17]3 years ago
5 0

Answer:

x = 12

Step-by-step explanation:

130 + y = 180   {linear pair}

          y = 180 - 130

         y = 50°

3x - 6 +8x + 4 + 50 = 180        {Angle sum property of triangle}

3x + 8x - 6 +  4 + 50 = 180          {Combine like terms}

          11x + 48          = 180

                    11x        = 180 - 48

                          11x = 132

                            x = 132/11

x = 12°

Johnnas reading rate is 150 words per minute she is reading a 364 page book that has about 275 words on each page at this rate w
ch4aika [34]

Answer:

11 hrs 1 min (i think so based on math)

Step-by-step explanation:

If Johnna's reading rate is 150 words per min and there are 364 pages with about 275 words, you need to multiply 364 and 275 to get 100100 and divide that by 150 to get 667.3333333 round to the nearest tenth which will give you 667.3 and divide that by 60 because there are 60 minutes in an hour to get 11.12222222 and round that to the nearest tenth to get 11.1 which means it will take Johnna 11 hours and 1 minute to read the book.  I hope this is correct I'm really sorry if it isn't. :P

Elizabeth works part-time to help pay for college. She has worked for the last 14 days without a day off for a total of 48 hours
Zinaida [17]
The answer if I am correct should be C. 6, since if you divide forty-eight by two you get twenty-four. Twenty-four divided by four equals six, and twenty-four divided by three equals eight, eight is the number that would be the remaining amount of days. Hope this helps you and have an amazing day!
