One hundred sixty-two guests attended a banquet. Three servers provided their beverages. The first server helped three times as many people as the second server and the third server helped twice as many people as the first server. How many guests did each server help?

Below given.

Step-by-step explanation:

162 total guests.3 servers

Let the number of guests the second server helped be x.

then the first server helped 3x

then the third server helped [(3x)*2] = 6x

Equation in total:

                               6x + 3x + x = 162

                                10x = 162

                                   x = 16.2

First server helped: 3 * 16.2 = 49 guestsSecond server helped: 16 guestsThird server helped: 6x = 6(16.2) = 97 guests

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
