9) a heptagon has 6 exterior angles with measures of 47, 55, 62, 64, 54, and 49. what
is the measure of the interior angle adjacent to the seventh exterior angle?

this doesn't make sense lol

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
