<h2>Answer: Choice A- 36</h2>

Step-by-step explanation:

<em>Create an equation for finding the measurement of angle x.</em>

<u><em>The interior angles of a triangle always add up to 180</em></u><em>°</em> while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°

We are given two out of the three angles. The first angle we are given measures 65° while the second angle measures 79°. Since all three angles always add up to 180°, we can add 65°, 79° and x° to equal 180°. This gives us the equation<em> 65 + 79 + x = 180. </em>

<em />

<em>Now solve for x. </em>

The first step in solving for <em>x </em>is combining like terms, so add <em>65 </em>and <em>79</em>. This gives us the equation <em>144 + x = 180</em>

<em />

The next step in solving for <em>x </em>is to get by itself on one side of the equation and to have the number on the other side of the equation by itself. In order to do this, subtract <em>144 </em>from each side of the equation to eliminate the number from the side with <em>x </em>in it.

This gives us the equation x = 36 which is our answer. The value of x is 36. Hope this helps, and have a great day!

65+79+x=180

(65+79)+x=180

144+x = 180

(144 - 144)+x= (180-144)

x=36

Please help with a math problem :/ Please show steps...<br><br> x^2 -13x = -36
Marianna [84]
X^2 -  13 x = -36 
add 36 to both sides

x^2 - 13x +36 = 0
figure out the factor
(x-4)(x-9) = 0
so (x-4) or (x-9) equals 0
so solution is
x-4=0 add 4 to both sides and get x = 4
x-9=0 add 9 to both sides and get x=9
x={ 4, 9}
