x y
_______A_________
/\
/ \
/ \
/ \
___/_______ \__
B C
we have two parellel lines xy and BC. It is true that:
xAy = 180°
xAB + BAC + CAy = xAy = 180
xAB = ABC
CAy= ACB
=> ........
I'll let you finish with your great intellect ^_^

Error = 60-50/50 × 100
= 10/50 × 100
= 20 %

Answer:
d. 16,848,000.
Step-by-step explanation:
First 3 characters is the number of permutations of 3 numbers from 10
= 10P3 = 10! / (10-3)! = 720 possible ways.
The next 2 characters are letters so the possible permutations are 26P2
= 26! / (26-2)! = 650 ways.
The last character can be any one of 10 + 26 = 36 characters.
So the answer is 720*650*36
= 16,848,000.
