Find the missing side of this right a triangle?<br> help pls
yaroslaw [1]

Hi, there!

 _____

To find the missing side length of this triangle (which is a <em>right</em> triangle), we'll use Pythagoras' Theorem.

-\!\!\!-\!\!\!-\!\!\!\longrightarrow\boldsymbol{a^2+b^2=c^2}

Here,

\textsc{legs:}\begin{cases} \bold{a}\\\bold{b} \end{cases}

Hypotenuse (the longest side): c

We know that

\bold{a=2 \ and \ b=28}

So, we can substitute our parameters, and solve for c.

\bold{2^2+28^2=c^2} -\!\!\!-\!\!\!-\!\!\!\longrightarrow square 2 and 28

\bold{4+784=c^2} -\!\!\!-\!\!\!-\!\!\!\longrightarrow add the numbers

\bold{788=c^2} -\!\!\!-\!\!\!-\!\!\!\longrightarrow square root both sides

\bold{\sqrt{788}=c}

Hope the answer - and explanation - made sense,

happy studying!!

jekas [21]

Answer:

The probability that the selected adult has liver problems is 0.08

Step-by-step explanation:

In this question, from the data given, we want to calculate the probability that an adult selected at random has liver problems.

Let E(L) be the event that an adult has liver problems.

The probability is directly obtainable from the question and it is given as 8%

Thus, the probability that the selected adult has liver problems; P(L) = 8% = 8/100 = 0.08
