faltersainse [42]
<h2>Answer:</h2>

In this exercise we have the following pattern:

1, -12, 12, -1

So we need to find the rule for this patter. First of all, let's take the first number, which is 1:

1

To find the second number, which is -12, we must subtract 13, because:

1 - 13 = -12

To find the third number, which is 12, we must add 24, because:

-12 + 24 = 12

In conclusion, the correct answer is A.) subtract 13, then add 24

find two complementary angles such that the measure of the first angle is X, and the measure of the second angle is ( 3X -2 )
mojhsa [17]

Step-by-step explanation:

<em>The </em><em>given </em><em>angles </em><em>are </em><em>complementary</em>

<em>Hence </em><em>sum </em><em>of </em><em>these </em><em>are </em><em>equal </em><em>to </em><em>9</em><em>0</em><em>°</em>

<em>X </em><em>+</em><em> </em><em>(</em><em> </em><em>3</em><em>X</em><em> </em><em>-</em><em> </em><em>2</em><em>)</em><em> </em><em>=</em><em> </em><em>9</em><em>0</em>

<em>X </em><em>+</em><em> </em><em>3</em><em>X</em><em> </em><em>-</em><em> </em><em>2</em><em> </em><em>=</em><em> </em><em>9</em><em>0</em>

<em>4</em><em>X</em><em> </em><em>-</em><em> </em><em>2</em><em> </em><em>=</em><em> </em><em>9</em><em>0</em>

<em>4</em><em>X</em><em> </em><em>=</em><em> </em><em>9</em><em>0</em><em> </em><em>+</em><em> </em><em>2</em>

<em>4</em><em>X</em><em> </em><em>=</em><em> </em><em>9</em><em>2</em>

<em>X </em><em>=</em><em> </em><em>9</em><em>2</em><em>/</em><em>4</em>

<em>X </em><em>=</em><em> </em><em> </em><em>2</em><em>3</em>

<em>First </em><em>angle </em><em>(</em><em>X)</em><em> </em><em>=</em><em> </em><em>2</em><em>3</em>

<em>Second </em><em>angle </em><em>(</em><em> </em><em>3</em><em>X</em><em> </em><em>-</em><em> </em><em>2</em><em> </em><em>)</em><em>=</em><em> </em><em>3</em><em>(</em><em>2</em><em>3</em><em>)</em><em> </em><em>-</em><em> </em><em>2</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em> </em><em>6</em><em>7</em>
