Answer:
The distance between X and Y is 68m
Step-by-step explanation:
Consider the diagram attached:
A person starts from X, goes to Y, and then finally goes to Z, covering a total of 100m, where Z is located 60m in north of X.
We have to find distance XY.
Let the distance XY be x
Total distance covered by the person = XY + YZ
We know that total distance covered is 100m, so
100m = x + YZ
YZ = (100 - x)m
See the diagram, XZY forms a right angled triangle such that:
Hypotenuse = XY = x
Base = XZ = 60m
Perpendicular = YZ = (100-x)m
Using Pythagoras theorem
Hypotenuse² = Base² + Perpendicular²
x² = (60)² + (100-x)²
Solve the equation for x, we get:
x = 68m
Answer:
Step-by-step explanation:
Think of this situation as a number line in which the team starts at 0 yd.
Gaining yards is the positive direction and losing yards is negative.
Start at 0 yd and go 5 yd to the right. You are at +5.
Then go 7 yd left. You end up at -2.
+5 – 7 = -2
We are given
first term is 1
so,
each succeeding term is found by adding 3 to the one before it
so, common difference is
Since, this is arithematic sequence
so, we can use nth terms formula
now, we can plug values
and we get
