Answer:

43°

Step-by-step explanation:

the blue angle is congruent with the 80° because they are vertical angles

the red angle is 57° because 123° and 57° angles are supplementary angles

the green angle is 43° because the sum or angles in a triangle is 180°

Answer:

  A: geometric; 4 times

  B: arithmetic: 4 more

Step-by-step explanation:

An arithmetic model is a linear model, where the rate of change is constant.  Growth or decay is by a constant amount from one interval to the next.

A geometric model is an exponential model, in which the rate of change is proportional to the amount. Growth or decay is by a constant factor from one interval to the next.

__

<h3>A)</h3>

The equation for the sequence is given in "explicit" form:

  A_n=2^{2n}

The exponent can be split so this can be rewritten as ...

  A_n=(2^2)^n=4^n

If this were written in recursive form, it would look like ...

  A_0=1,\ A_n=4\times A_{n-1}

The fact that terms are related by a constant factor tells you the model is geometric. The factor tells you each hour the population is 4 times what it was in the previous hour.

__

<h3>B)</h3>

The given equation is in "recursive" form. It tells you each term is 4 more than the previous one. This constant difference between terms means the model is arithmetic.

_____

<em>Additional comment</em>

In general, words like "more" or "increase" refer to addition, and the words "times" or "factor" refer to multiplication.

Answer:

cost of tacos=$2

cost of soda=$1

Step-by-step explanation:

x=price of tacos

y=price of soda

3x+y=7 --> y=7-3x

4x+2y=10 --> y=5-2x

5-2x=7-3x

x=2

y=5-2(2)=1

How do you find the exterior angle of a polygon?
trasher [3.6K]

The sum of the measures of the interior angles of a polygon with n sides is (n – 2)180.

The measure of each interior angle of an equiangular n-gon is.

If you count one exterior angle at each vertex, the sum of the measures of the exterior angles of a polygon is always 360°.
