Ответ:
5. x = 39°
6. x = 46°
7. x = 24°
8. x = 19°
Step-by-step explanation:
5.
Base angles are the same due to it being an isosceles triangle
Sum of angles in triangle = 180°
2x + 2x + (x - 15) = 1804x + x - 15 = 1805x - 15 = 1805x = 195x = 396.
Angle VZW and XZW are supplementary, meaning that they add up to 180°
3x + 17 + (x - 9) = 1803x + 17 + x - 9 = 1804x + 8 = 1804x = 184x = 46°7.
Sum of angles in a straight line add up to 180°
(2x - 4) + (3x + 5) + (2x + 11) = 1802x - 4 + 3x + 5 + 2x + 11 = 1807x + 12 = 1807x = 168x = 248.
All angles add up to 90°
x + (x + 4) + (3x - 9) = 90x + x + 4 + 3x - 9 = 905x - 5 = 905x = 95x = 19-Chetan K
Ответ:
16 ounces > 12 $
1 ounces > x
Clearing x we have:
x = (1/16) * (12)
x = 0.75 $ / ounce
The price, in dollars, per ounce of confetti is:
x = 0.75 $ / ounce
