sweet-ann [11.9K]

Answer:

25 miles

Step-by-step explanation:

Given: A boat sail 20 miles west of the port and then 15 miles south to an island.

Picture attached.

The distance from port to island could be measured in a straight line. It will form a hypotenous.

∴ we can use Pythogorean theorem to find the distance.

h^{2} = a^{2} +b^{2}

Where, "a" is adjacent= 20 miles and "b" is opposite= 15 miles.

h^{2} = 20^{2} +15^{2}

⇒ h^{2} = 400+225= 625

⇒h^{2} = 625

⇒h= \sqrt{625}= \sqrt{25^{2} }

We know \sqrt{x^{2} } = x.

∴h= 25\ miles

∴ Distance of Port from the Island is 25 miles.

How to subtract unlike fractions
topjm [15]
Find the common denominator for both unlike fractions.

EX:   1                        2
         12                      8

The lowest common factor is both fractions is 24.           Multiply both denominators to get 24. 

Do not forget to multiply the numerators with the number you used to multiply the denominators together.        

You do not have to multiply each side by the same number.
