Answer:
tan ^(-1) (6/7)
See attached picture.
Step-by-step explanation:
In a right triangle, tan(∅) = opposite / adjacent. The function tangent finds the side ratio for a specific angle. Here, the side opposite the Angle N is 6. The side adjacent to Angle N is 7. This means tan N = 6/7.
However, we want to find the angle using the side ratio (we already have the ratio). To find N, use the inverse function tan ^(-1). It becomes N = tan ^(-1) 6/7.
The answer is 7
There is no need for explaining cause you can minus -2 and 5 to get x+7
Answer: 13. -68
14. 36
15. -36
16. -3
17. 10
18. -4
19. 1310 ft
20. 330 ft
Step-by-step explanation:
13. 34*(-2)=-68
14. -9*(-4)=
-(9*(-4))=
-(-36)=36
15. 12*(-3)=-36
16. -12/4=-3
17. -20/(-2)=
20/2=10
18. 200/(-50)=-4
19. -1640*(-1)-(-330*(-1))=
1640-(-330*(-1))=
1640-330=1310 ft
20. -990*(-1)-(-660*(-1))=
990-(-660*(-1))=
990-660=330 ft
