Aboats sail is a right triangle . the length of one side of the sail is 7 feet more than the other side . the hypotenuse is 13 feet . find the lengths of the two side of the sails

The lengths of the two side of the sails are 5 feet and 12 feet

A boats sail is a right triangle

The diagram is attached below

ABC represents the right angled triangle

AC represents hypotenuse

AC = 13 feet

AB and BC are the other two legs of right angled triangle

Let BC = "a"

So by given length of one side of the sail is 7 feet more than the other side

So AB = a + 7

To find: lengths of the two side of the sails

We have to find length of AB and BC

By pythagoras theorem,

The square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.

So above definition we can say,

Substituting the above values of AB = a + 7 and BC = "a" and AC = 13

Dividing each term by 2

Using factoring method to solve this quadratic equation,

"7a" can be written as 12a - 5a

Taking "a" as common from first two terms and -5 as common term from next two terms

a(a + 12) -5(a + 12) = 0

Taking (a + 12) as common term,

(a + 12)(a - 5) = 0

Equating each term to zero,

a + 12 = 0 or a - 5 = 0

a = -12 or a = 5

Since length cannot be negative, so ignore a = -12

Thus length of BC = "a" = 5

And length of AB = a + 7 = 5 + 7 = 12

Thus the lengths of the two side of the sails are 5 feet and 12 feet

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
