Correct option: (A) Someone with dangerous material that pass through security.
Before boarding a flight every person has to pass through airport security.
The security checks every person thoroughly before they are confirmed as safe to go.
The security checks every person for some harmful substances like, weapons, chemical,etc.
If a person is caught with any of these objects the security stops them from boarding the plane.
So if a person is flagged as a risk by the airport security, he/she should have been carrying any kind of harmful substances.
Thus, the correct option is (A).
y = 70°
Complementary angles sum to 90°, then
x + y = 90°, that is
20° + y = 90° ( subtract 20° from both sides )
14 and 9 have no GCFs (Greatest Common Factors), so the ratio is simply 14/9.
12 times 2 equals 24
12 times 15 is 180
180 divided by 90
