Answer:
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) = 180
- 4x + x - 15 = 180
- 5x - 15 = 180
- 5x = 195
- x = 39
6.
Angle VZW and XZW are supplementary, meaning that they add up to 180°
- 3x + 17 + (x - 9) = 180
- 3x + 17 + x - 9 = 180
- 4x + 8 = 180
- 4x = 184
- x = 46°
7.
Sum of angles in a straight line add up to 180°
- (2x - 4) + (3x + 5) + (2x + 11) = 180
- 2x - 4 + 3x + 5 + 2x + 11 = 180
- 7x + 12 = 180
- 7x = 168
- x = 24
8.
All angles add up to 90°
- x + (x + 4) + (3x - 9) = 90
- x + x + 4 + 3x - 9 = 90
- 5x - 5 = 90
- 5x = 95
- x = 19

Answer:
4d + 6
Step-by-step explanation:
Helen ate d donuts.
Andrea ate 6 more than 4 times d.
4d + 6
Step-by-step explanation: P is how much in all
6 is what is taken away.
P minus 6 = 11
P - 6 = 11
How many pairs did they start with?
6 + 11 = 17
ANSWER: 17 Proof : instead of P put 17: 17 - 6 = 11
