Answer:
x = 32
Step-by-step explanation:
∠BCA = ∠DBA (90 - ∠DBC)
∠A = ∠A
ΔABD similar to ΔACB
AC/AB = AB/AD
x / 8 = 8 / 2
x = 32

Answer:
The number of kids NOT wearing socks in the gym = 20
Step-by-step explanation:
Here, the total number of kids in the gym = 80
Now, 75% of the kids are wearing socks.
Let us assume the number of kids wearing socks = m
⇒ 75 % of 80 = m
Calculating the value of m ,we get:

⇒ 60 kids are wearing socks.
Kids not wearing socks = Total kids in gym - Kids wearing socks
= 80 - 60 = 20
Hence, the number of kids NOT wearing socks in the gym = 60.
