10 ! (To find the median add the two middle numbers 7,13 = 20 divide 20 by two and you get 10 as your median. Mode means the most common number which means the mode is also 10)
Answer:
x = 75°
Step-by-step explanation:
Sum of angles in a triangle: 180°
So,
50°+55°+x=180°
105°+ x = 180°
Subtract 105° from both sides
x = 75°
Daniel -- 12 balls
Manuel -- 12 balls × 2 = 24
Kendra -- 24 balls x 2 = 48
12 + 24 + 48 = 84 balls total
