Answer:
53
Step-by-step explanation:
x - the age of the person who entered the room.
(12 + 19 + 24 + 21 + 21 + x)/6 = 25
12 + 19 + 24 + 21 + 21 + x = 150
97 + x = 150
x = 53
<1 = 123
60 + 63 = 123
180 - 123 = 57
180 n- 57 = 123
Triangle angle-sum theorem
Alternate exterior angles theorem (?)
Same side interior angles theorem
idk what the last one is about sorry
hope this helps
