2x² + 5x -6x - 15 = 0
2x² - x - 15 = 0
2x² -x = 15
x = 3
3 x 3 = 9 x 2 = 18 - 3 = 15
i really don't know how i got 3 in the first place but that is your answer
hope this helps
The exterior angle theorem states that the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles.
In the given problem, x represents the exterior angle, while the m < 65° and m < 48° are the non-adjacent interior angles.
To find the value of x:
65° + 48° = x
113° = x
Therefore, the value of x = 113°
To get X by itself you first bring -7 over and get X/5=-1 then multiply both sides by 5 to get X=-5
The answer should be c hope this helps
