Answer:
Step-by-step explanation:
Angles 153 and QRP are straight angles, and thus Angle QRP is
180 - 153, or 27 degrees.
The interior angles of the triangle must sum up to 180 degrees:
27 + (3y + 5) + (2y - 7) = 180.
combining like terms, we get:
5y - 25 = 180, or 5y = 155, or y = 31
Then Angle Q is 3(31) + 5, or 93
Angle P is 2(31) - 7, or 55, and
Angle QRP is 27 degrees (found earlier).
60 divide dos by 15 is 4, so it takes 4 minutes for each person to empty it.
25 x 4 = 100, so the answer would be 100 minutes.
17, you only have to add up a few because of the x and y placements. Hope this helps you :)
