Answer:
b. none
Step-by-step explanation:
An angle has internal angles adding to 180º.
Those angles only add to 170º so no triangle can be made.
Thousand = 4
round off = 955 000
No because you are distributing and for 3(x+11/2), you multiply 3 times x is 3x and then 3 times 11/2 is 16 1/2 . All together 3x+16 1/2 or 16.5
It is not equal to 3x+11/2.
There is .82% chance they will have the same bdays
