The image shows that all integers are rational numbers, but there are rational numbers that are not integers.
The formal statement would be

Answer:
A
Step-by-step explanation:
Option C is the right way to solve the equation.
Answer:
tan T = 3/4
tan U = 4/3
Step-by-step explanation:
The tangent ratio is opposite / adjacent. The ratio will vary for each angle since the perspective of each angle will be different. For example Angle T has an adjacent side of 4 while Angle U has an adjacent side of 3. The tangent ratios for Angles U and T are listed below:
tan T = 3/4
tan U = 4/3
