2. saifoo.khan

Just a sec.

3. saifoo.khan

4. lvasquev462

yes

5. saifoo.khan

So, for the first one it's angle 4.

6. saifoo.khan

For question 2, it's asking for complimentary angle of angle 3. Complimentary agnles add upto 90* So, it's angle 2.

7. saifoo.khan

For question 3. Vertically opposite angles are equal of each other|dw:1348279518333:dw|

8. saifoo.khan

Therefore, 2 and 5 are v.o.a.

9. lvasquev462

ok..

10. saifoo.khan

Moving along. Question 4. Solve for x.

11. saifoo.khan

Rest all are easy too!

12. lvasquev462

solve for x right

13. saifoo.khan

Yup.

14. lvasquev462

what did you get? I want to check if i got it right

15. saifoo.khan

What do you get?

16. lvasquev462

30

17. saifoo.khan

\[\checkmark\]

18. lvasquev462

so its 30 degrees right

19. saifoo.khan

Right.

20. lvasquev462

21. saifoo.khan

Thank you! :)

22. lvasquev462

number 5?

23. saifoo.khan

So i have to do all of them? lol. How about you give them a try and i check your answers?

24. lvasquev462

how about 1 more 1 last one can you do number 9

25. saifoo.khan

Break the problem into parts..

26. lvasquev462

i want a 100percent on this assignment it will bring me to a B

27. saifoo.khan

They all are easy, you'll get it.

28. saifoo.khan

Suppose the angle be x. And since it's a supp. angle, hence (180 -x) And since it's 3 times of that, 3(180-x) And as it's 20 less out of it.. so: x=3(180-x) - 20 x=540-3x-20 4x=520 x=130*

29. lvasquev462

is this 9

30. saifoo.khan

Now let's check: If x is 130, then the supp angle of x is 180-130 = 50. Three times the supplement of x is 3*50 = 150. And 20 less than that is 150-20 = 130.

31. saifoo.khan

And yes, it's 9.

32. lvasquev462

thank you i really appreacitae it

33. saifoo.khan

You're welcome.

34. lvasquev462

is number 5 30 degrees ?

35. saifoo.khan

Nope.

36. saifoo.khan

The answer is not given. It's 120*.

37. lvasquev462

is number 6 B

38. lvasquev462

1and5

39. saifoo.khan

6 is b

40. lvasquev462

and number seven i gotten 6x - 40 = 3x + 5 6x - 3x = 5 + 40 3x = 45 x = 15 deg

41. saifoo.khan

correct

42. lvasquev462

number 8 y + 3x = 180 3x = 75 y + 75 = 180 y = 105 deg

43. saifoo.khan

3x = 75 x = 75/3 x = 25

44. lvasquev462

can u check my work if i copy the docment

45. saifoo.khan

Sure

46. lvasquev462

ok
