Q# 25 find the distance between the two points

To find the distance between the points given in the figure of the problem above, you must apply the formula for calculate the distace between two points, which is shown below:
 d=√[(x2-x1)^2+(y2-y1)^2]
 When you substitute the values, you obtain:
 d=√[(x2-x1)^2+(y2-y1)^2]
 d=√[(-1-2)^2+(-5-5)^2]
 d=10.4
 The answer is:10.4

It will take him 5 days

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
