The sides of a parallelogram are 14ft and 16ft. One angle is 41° while another angle is 139°. Find the lengths of the diagonals
Semenov [28]

We will have the following:

First, we have that the problem can be seeing as follows:

Now, knowing this and the the properties of the diagonals we will have that [We use the law of cosines}:

First diagonal [AC} is given by:

\begin{gathered} AC=\sqrt{16^2+14^2-2cos(41)}\Rightarrow AC=10.67193085... \\  \\ \Rightarrow AC\approx10.7 \end{gathered}

So, one of the diagonals has an approximate length of 10.7 ft.

Second diagonal [BD] is given by:

\begin{gathered} BD=\sqrt{16^2+14^2-2(16)(14)cos(139)}\Rightarrow BD=28.10889347... \\  \\ \Rightarrow BD\approx28.1 \end{gathered}

So, the second diagonal has a length of approximately 28.1 ft.

<em>**Diagonals**</em>

\begin{gathered} AC\approx10.7ft \\  \\ BD\approx28.1ft \end{gathered}

A television game show has 12 ​doors, of which the contestant must pick 3. Behind 3 of the doors are expensive​ cars, and behind
almond37 [142]

The probability that the contestant wins at least one car is 3/5.

<h3>What is the probability?</h3>

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

For 1 car, we consider two possible outcomes:

P(1 car) = 2/6 x 4/5 + 4/6 x 2/5

P(1 car) = 8/15

For no car in either door

P(no car) = 4/6 x 3/5

P(no car) = 2/5

The probability that the contestant wins at least one car is the sum of the probability of one car and the probability of two cars:

P(2 cars) = 2/6 x 1/5

= 1/15

P(1 car) + P(2 cars) = 8/15 + 1/15

= 3/5
