Answer:
From the given figure we can see that :---
MN||PO, MN=PO and MP=NO
Therefore, angle M=angle N (adjacent sides of the trapezoid)

angle M=angle N= (6×18)+20=108+20 =128°
angle O =(180°-128°)=52°
<h3>Hence, angle O is <u>52°.</u></h3>
The value is the tens place

Given that there are 13 people at the party, and each of them will bring a gift, by mathematical logic there will be 13 gifts distributed in the party.
found this online, hope it helps !!
M + R + G = 119
G = 3M
M = R + 6 —> R = M - 6
1st equation: M + (M-6) + (3M) = 119
5M -6 = 119
5M = 125
M = 25
G = 3(25) = 75
R = (25) -6 = 19
