Question

A sailboat's Saul has three sides that are all the same length. Each side measures x - 10 units. The sail's perimeter is 63 units. What is the value of x?

Answer 1

The value of 'x' is 31 unit

Explanation:

Given:

Measure of each side =
`x-10\ units`

Perimeter of sails = 63 units.

We need to find the value of x.

Solution:

Now we can see that from given data.

A sailboat's Saul has three sides.

Now assuming it to be triangle we get;

"Perimeter of triangle is equal to sum of all side."

So we can say that;

`x-10+x-10+x-10 =63\\\\3x-30=63`

Now adding both side by 30 we get;

`3x-30+30=63+30\\\\3x=93`

Now dividing both side by 3 we get;

`(3x)/(3)=(93)/(3)\\\\x=31 \ units`

Hence the value of 'x' is 31 units.
