Step-by-step explanation:
Since they are complementry angles :
(12x-9) + (8x + 14) = 90°
20x + 5 = 90°
X = 4.25 °
Angles are 42° and 48°.
Answer:
<h2>The completed factor is

</h2>
Step-by-step explanation:
To factor the expression we need to look for a value that is unique to both terms in the expression.
Given the expression
The available factors common to both terms are 2,3,4,6,8,12. but since we are expected to factor the expression completely we will use the greatest common factor (gcf) to find the solution
The greatest but common factor is 12, hence we have

5x^2 -2x +1 = 0
D = 4 -20 = -16
so this mean that the quadratic has no real solutions
