Answer:
1. x = 3
2. (1, 0)
3. x = 3, -2
4. 144
5. -3 <u>+</u> 4√3
Step-by-step explanation:
15x - 30 = 10x + 5
15x - 10x -30 = 5
5x - 30 = 5
5x = 5 + 30
5x = 35
Divise by 5 on both sides to isolate x
x = 7 => answer
The Angles are adjacent and since they are both on a straight line it means that the sum of the angle is 180 degrees, so we get the equations:

So x = 26.
