I'll do the first problem to get you started.
Triangle SRT is a right triangle with the 90 degree angle located at angle RST. This is because segment SR is an altitude of the triangle. Altitudes of a triangle go from a vertex to the opposite side, and they are perpendicular to the opposite side.
The acute angles of right triangle SRT add up to 90 degrees. They are complementary angles.
(angle SRT) + (angle STR) = 90
(4x-8) + (6x+13) = 90 .... substitution
10x + 5 = 90
10x + 5 - 5 = 90 - 5 .... subtract 5 from both sides
10x = 85
10x/10 = 85/10 .... divide both sides by 10
x = 8.5
Therefore the answer is choice A) x = 8.5

Step-by-step explanation:
Answer:
Correct option: (A) Someone with dangerous material that pass through security.
Step-by-step explanation:
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).
The mixed number is 4 5/12.
