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
Answer:110 degrees
Step-by-step explanation:
L1 and L2 are parallel so the angle above angle 1 is 70 degrees too. Then the angle that is right next to that 70 degrees is 110 because a straight line equal 180 degrees. And whatever angle that is diagonal from angle 1 is the same degrees. So, since it's 110 degrees diagonal from angle 1 then angle 1 is also 110 degrees.
