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

Mathematics

Ray Of Light [21]3 years ago

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>

Answer:

10d or less

Step-by-step explanation:

Joanne would want $50 left, and she has $250. 20 - 50 is 200. 20 goes into 100 5 times.

20 goes into 200 10 times. You just add five. (20, 40, 60, 80, 100)

If she wants at least $50 left, she would have to limit how many Dvd's she buys to 10 or less.

Richie spent $120 on 12 rose bushes and 2 gardenias, while Jim spent it $150 on 10 rose bushes and 10 gardenias. What is the cos
Basile [38]
With the given information, we can create several equations:

120 = 12x + 2y
150 = 10x + 10y

With x being the number of rose bushes, and y being the number of gardenias.

To find the values of the variables, we can use two methods: Substitution or Elimination

For this case, let us use elimination. To begin, let's be clear that we are going to be adding these equations together. Therefore, in order to get the value of one variable, we must cancel one of them out - it could be x or y, it doesn't matter which one you decide to cancel out. Let's cancel the x out:

We first need to multiply the equations by numbers that would cause the x's to cancel out - and this can be done as follows:

-10(120 = 12x + 2y)
 12(150 = 10x + 10y) => Notice how one of these is negative

Multiply out:

    -1200 = -120x - 20y
 +  1800 =  120x + 120y          => Add these two equations together
---------------------------------
600 = 100y

Now we can solve for y:

y = 6

With this value of y known, we can then pick an equation from the beginning of the question, and plug y in to solve for x:

120 = 12x + 2y    =>    120 = 12x + 2(6)

Now we can solve for x:

120 = 12x + 12    =>     108 = 12x

x = 9

So now we know that x = 9, and y = 6.

With rose bushes being x, we now know that the cost of 1 rose bush is $9.
With gardenias being y, we now know that the cost of 1 gardenia is $6.
