- Between two lines m ║ n, the ∦ cuts through them forming two angles
- As it forms a line, the sum of the angles is 180°
- 3x + 47 + x + 7 = 180
- 4x + 54 = 180
- 4x = 126
- x = 126/4 = 63/2 = 31.5
15.
- Alternate exterior angles on a transversal are equal
- 5x = 2x + 78
- 3x = 78
- x = 26
Answer: 12x+15y
Step-by-step explanation:
Answer:
x = 2 1/ 2 , − 1 1/2
Step-by-step explanation:
The answer to question one is left to right
The A, the C and the D because we have the vectors YX and YW which start from Y and the angle XYZ because the angle is around Y
