The external angle is suplementary to the internal angle close to it. We also know that the sum of all the internal angles of the triangle are equal to 180 degrees, this means that the angle "a" is suplementary to the sum of the angles "b" and "c". Through this logic, we can conclude that since:

\begin{gathered} \angle d=180-\angle a \\ \angle b+\angle c=180-\angle a \end{gathered}

Then we can conclude that:

\angle d=\angle b+\angle c

Therefore the statement is true, the exterior angle is equal to the sum of its remote interior angles.

Let's use an example:

On this example, the external angle is 120 degrees, therefore the sum of the remote interior angles must also be equal to that. Let's try:

x=75+45=120

The sum of the remote interior angles is equal to the external angle.

Cam is a corrupt politician. Nobody votes for him except those he pays to do so. It costs Cam exactly \$100$100 to buy each vote
dolphi86 [110]

Answer:

Yes, Cam's costs proportional to the number of votes he receives.

Step-by-step explanation:

It is given that Cam is a corrupt politician. Nobody votes for him except those he pays to do so. It costs Cam exactly $100 to buy each vote.

Let the number of votes he get be x.

Then the total cost of Cam is

C=100\times x         ... (1)

Where, C is Cam's costs and x is number of votes he receives.

Two variables are proportional to each other if

y\propto x

y=kx                     ... (2)

Where k is constant of proportionality.

Since equation (1) and (2) and similar and the constant of proportionality is 100, therefore we say that Cam's costs proportional to the number of votes he receives.
