Answer:
- Q6. x = 17
- Q8. Yes, parallel
- Q9. No, not parallel
Step-by-step explanation:
Q6. Solve for x
<u>Use ratios of similar sides</u>
- 28/(82 - 28) = (2x + 8)/(5x - 4)
- 28/54 = (2x + 8)/(5x - 4)
- 14/27 = (2x + 8)/(5x - 4)
- 14(5x - 4) = 27(2x + 8)
- 70x - 56 = 54x + 216
- 70x - 54x = 56 + 216
- 16x = 272
- x = 272/16
- x = 17
Q8
If ratios are same, the lines are parallel
- 41.8/33 = (102 - 45)/45
- 41.8/33 = 57/45
- 41.8*45 = 33*57
- 1881 = 1881
Yes, lines are parallel
Q9
Incorrect, lines are not parallel

Answer:
θ = 280°
Step-by-step explanation:
We assume your intended equation is ...
θ = 14π/9 . . . . radians
π radians is 180°, so we can simply put 180° where π is in your equation.
θ = 14(180°)/9
θ = 280°
Answer:
For number two, nearest whole number is 13. nearest hundredth is 13.26. number three I don't see anything.
Step-by-step explanation:
Explanation: When rounding, u look at the right number and if
greater than 4, round up which is add one
if right number is 4 or less we take nothing. also we change all other numbers behind the left number to 0. so round to a whole number it would be 13. 2 is smaller than 5. Nearest hundredth is the same thing. we look at the hundredth place which is 6. We look to the right. it's 0. less than 5 we round down. so it would be 13.2600. Or 13.26
number 3 I don't see anything so I can't help out
