Answer:

7.8 cm and 25.3 cm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

?² + 7² = 10.5²

?² + 49 = 110.25 ( subtract 49 from both sides )

?² = 61.25 ( take the square root of both sides )

? = \sqrt{61.25} ≈ 7.8 cm ( to 1 dec. place )

Then

P = 10.5 + 7 + 7.8 = 25.3 cm

anygoal [31]

Answer:

51m

Step-by-step explanation:

For this equation, you want to use pythagoras' theorem (or pythagorean theorem) to work out the hypotenuse (diagonal line)

The formula for this is a²+b²=c², where c is the hypotenuse.

We can sub in the 2 sides for a and b, turning the equation into 24²+45²=c².

Working out the squares gives 576+2025=c², which can be solved to c²=2601.

To get c, we must square root both sides, which results in c=51m.

**This question involves pythagoras' theorem, which you may wish to revise. I'm always happy to help!

Fifteen years later, a man will be two times as old as he was 15 years ago. How old is he now?
Inga [223]

Answer:

Let the present age of the man be x years.

Age of the man 15 years ago =(x−15) years and

Age of the man 15 years later =(x+15) years

According to the given condition, we have

(x+15)=2(x−15)

⇒x+15=2x−30

⇒x−2x=−30−15

⇒−x=−45 or x=45 years

Hence, the present age of the man is 45 years.

Step-by-step explanation:

Hope it helps you..

Your welcome in advance..
