Step-by-step explanation:
Any number divided by itself equals 1. So, 23 divided by 23 is 1.
A graphing calculator is a great help for problems of this nature.
x ∈ {-5.63, -0.55, 2.59}
Answer:
x= 55
Step-by-step explanation:
The two angles add to 180 degrees since they form a straight line
2x+70 =180
Subtract 70 from each side
2x+70-70=180-70
2x= 110
Divide by 2
2x/2 = 110/2
x= 55
