a = √10
hope this helps :)
He went 41 miles altogether, because 10+30+1=41
Answer:
36 degrees
Step-by-step explanation:
A+B=90
A-B=18
add these two equations:
2A = 108
A=54
B=36
Given, (0,−2).
Since the x-coordinate is 0, the point clearly lies on y-axis.
Also, the y-coordinate −2 being negative, the point lies on the negative y-axis.
