Answer: <span>A. about 30.8 miles
</span><span>
The x and y distance from the campsite at A (3, – 5), and the next checkpoint station is located at B (–10, 1) would be:
Xab= Xb- Xa= -10 - 3= -13
Yab= Yb- Ya= 1- (-5)= 6
The resultant distance would be
c^2= a^2+b^2
c^2= (-13)^2 + (6)^2
c= </span>√(169+36)= √205
c=14.32
If each unit in the coordinate plane represents 2.15 miles, the true distance= 14.32*2.15 miles= 30.78 miles
As OB is the perpendicular bisector of AD. So AO = OD
Hence
2x + 5 = 3x – 5
3x – 2x = 5 + 5
<span>x = 10</span>
The value of Angle Y is 100 because a triangle is 180 degrees and angle c is 80 which means 180 minus 80 equals 100
