Find the measure of the exterior angle x
Ksivusya [100]

The measure of the exterior angle x is 90°.

We need to find the measure of the exterior angle x.

<h3>What is the exterior angle theorem formula? </h3>

An exterior angle of a triangle is equal to the sum of its two opposite non-adjacent interior angles.

Now, x°=∠A+∠B

⇒x°=30°+60°=90°

Therefore, the measure of the exterior angle x is 90°.

Noah and William play a game by rolling the die. If the die shows 1, 2, 4, or 5, then they will win $3. Otherwise, they will los
Serjik [45]

Given:

die is 1,2,4,5 win amount is $3.

otherwise lose is $1.

Probability for win is:

Number of favorable outcome is =4

total out come is :6

so probability is:

\begin{gathered} P(A)=\frac{Number\text{ of favorable outcome}}{total\text{ outcome }} \\ =\frac{4}{6} \end{gathered}

Amount is:

\begin{gathered} =3\times\frac{4}{6} \\ =\frac{12}{6} \end{gathered}

Probability for lose is:

Number of favorable outcome is:2

Total outcome is:6

so probability is:

P=\frac{2}{6}

So amount is:

\begin{gathered} A=1\times\frac{2}{6} \\ =\frac{2}{6} \end{gathered}

so total amount is:

win-lose amount :

\begin{gathered} \text{Expected value =}\frac{\text{12}}{6}-\frac{2}{6} \\ =\frac{12-2}{6} \\ =\frac{10}{6} \end{gathered}
