you would us the pythagorean theorem to solve this. a^2 +b^2=c^2
a and b being the width and the length and c being the diagonal or hypotenuse.
7^2 + 24^2 =c^2
49 + 576 = C^2
625 = C^2 take the square root of both sides to get
C = 25 feet
Assuming that all of them can sail the boat. For them to sail to the island.
First: The two children (Nancy and Peggy) should sail to the island.
Next: One of the children (say Nancy) should bring back the boat.
Next: One of the adults (say Uncle Jim) should sail to the island.
Next: The other child (Peggy) should bring back the boat.
Next: The two children should sail to the island.
Next: One of the children should bring back the boat.
Next: The remaining adult (the mother) should sail to the island.
Next: The other child should bring back the boat.
Finally: The two children should sail to the island.
Answer:
x = 50
Step-by-step explanation:
In a polygon, the angles add up to 360°:
x + 10 + 2x + 3x + x = 360
7x + 10 = 360
7x = 350
x = 50
