Answer:

\sqrt{8^{2} + 3^{2} }

Step-by-step explanation:

We see that this is a rectangle triangle, and that the ZY side is the hypotenuse.

It's length is then square root of the sum of the squares of the other sides:

hyp = \sqrt{a^{2} + b^{2} }

So, in this case:

ZY = \sqrt{8^{2} + 3^{2} }

The 8 and 3 numbers are easy to get from the graphic... and the order doesn't matter (8² + 3² = 3² + 8²).

That's an easy rule to remember.

I hope it helps.

Answer:

|ZY|=\sqrt{8^2+3^2}

Step-by-step explanation:

ZY is the hypotenuse of triangle XZY.

The two shorter legs are;

YX=3 units

and

XZ=8 units.

According to the Pythagoras Theorem;

|ZY|^2=|XZ|^2+|YX|^2

This implies that;

|ZY|^2=8^2+3^2

We take the positive square root to obtain;

|ZY|=\sqrt{8^2+3^2}

The second choice is correct

An athlete jumped 5.5 feet which was 1.1 times higher than the previous jumper how high did the previous athlete jump
Fantom [35]

Answer:

5 ft

Step-by-step explanation:

Let the height of the previous jump be represented by j.  Then 1.1j = 5.5 ft.

Dividing both sides by 1.1, we get j = 5 ft.  This was the height of the previous jump.

Solve each proportion, round to one decimal place.<br> 4/9=x/20
guapka [62]

In order to solve a proportion you need to cross multiply, so you would do:

4x20 and 9xX and you would get...

9x=80

then divide by nine to get

x=8.8888888889

which is technically 8.9
