Tanα=5/12
α=arctan(5/12)°
α≈22.62° (to nearest hundredth of a degree)

Answer:
1 2 3 4 5
4 8 12 16 20
Step-by-step explanation:
the x is 4 therefore, count by 4.
Answer:
Option B is correct.
Reason:It is an argument
Step-by-step explanation:
Given:
and 
By transitive property: a = b and b = c then, a =c
⇒
AB = EF [def of
segment]
By Segment Addition Postulate states that given two points A and C, and a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation
AB + BC = AC.
Since, the line segment EG , F lies on the line segment;
then, by segment addition postulates we have;
EG = EF + FG
By substitution AB=EF
⇒ EG = AB + FG hence proved!
Since, in the fourth statement reason is: It is an argument
Student's error is –5 < x.
Solution:
Step 1: Given inequality
31 < –5x + 6
Step 2: Subtract 6 from both sides of the inequality.
31 – 6 < –5x + 6 – 6
25 < –5x
Step 3: Multiply both sides by –1 to reverse the inequality.
25 × (–1) > –5x × (–1)
–25 > 5x
Step 4: Divide by 5 on both sides.
–5 > x
The correct answer is –5 > x.
Student's error is –5 < x.
