What is the length of the unknown leg in the right triangle?

Pythagorean theorem: ⇒ a²+b²=c²

A unknown leg of a right triangle can be found using the Pythagorean theorem.

a²+b²=c²

a²+9²=√113²

You had to solve by the equation with exponents.

And it gave us ⇒ a²+81=113

And then you had to subtract by eighty-one (81) from both sides of equation form.

And it gave us ⇒ a²=32

And finally you had to used their square root with thirty-two (32) from both sides of equation form.

And it gave us ⇒ a²=32, \sqrt{a^2}= \sqrt{32}, and a=\sqrt{32}.

<u><em>32 miles is the correct and final answer. </em></u>

Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

So for this, we will be using the pythagorean theorem, which is leg^2+leg^2=hypotenuse^2 , to find the missing leg. Since we know that a and 9 are our legs and √113 is our hypotenuse, plug them into the equation as such:

a^2+9^2=\sqrt{113}^2

Firstly, solve the exponents:

a^2+81=113

Next, subtract 81 on both sides of the equation:

a^2=32

Next, square root both sides of the equation:

a=\sqrt{32}

<u>Your final answer is √32 miles.</u>

9. Which of the following is true about the Venn diagram below?
bonufazy [111]

Answer:

(d) All of the above

Step-by-step explanation:

In order to solve this question we will have to find out which numbers are located in which group (the group of numbers are U, B, B').

So lets start of with finding out what numbers are a part of group U. By looking at that picture we can see that all number on the graph are a part of group U. So.....

U = {0,1,2,3,4,5,6,7,8,9}

Then we can find out what numbers are part of the group B. We just have to include the numbers that are located within the circle and exclude all of the numbers out side of the circle. So........

B = {0,1,4,5,6,7,8}

We find numbers that are parts of group B' by using a similar method that we used to find out what numbers were part of group B (Just this time we include all numbers outside of the circle and exclude all of the numbers inside the circle). So ......

B' = {2,3,9}

Now we see that the right option is option d.
