Answer:
x=27
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
90 + x+23 + x+13 = 180
Combine like terms
126 +2x = 180
Subtract 126 from each side
126-126 +2x=180-126
2x =54
Divide by 2
2x/2 = 54/2
x = 27
The factors of the quadratic equation are (x+3) and (x-15).
<h2 /><h2>Given to us</h2>
<h3>To find</h3>
The factors of
.
<h3 /><h3>Solution</h3>

As we can see in the quadratic equation the value of ac is -45x². therefore, we need to divide -12x into two parts such that their sum must give -12x and their product gives us -45x².
therefore, dividing -12x into -15x and 3x,

Taking common out,

Hence, the factors of the quadratic equation are (x+3) and (x-15).
