The figure below shows parallel lines cut by a transversal:

A pair of parallel lines is shown, cut by a transversal. Angle 7 is located in the upper right exterior corner on the top line, and angle 8 is located in the upper left exterior corner of the top line.
Which statement is true about ∠7 and ∠8? (4 points)

∠7 and ∠8 are supplementary because they are a pair of corresponding angles.
∠7 and ∠8 are complementary because they are a pair of adjacent angles on a straight line.
∠7 and ∠8 are congruent because they are a pair of adjacent angles on a straight line.
∠7 and ∠8 are supplementary because they are a pair of adjacent angles that form a straight line.

D Sorry if I am wrong mark me brainleist is right

Step-by-step explanation:

When two adjacent angles are formed at a point on a line so that sum of their measures is 180°, angles are called as supplementary to each other.

In the figure attached, ∠7 and ∠8 are supplementary because they are a pair of adjacent angles that form a straight line.

a is the answer

Step-by-step explanation:

I know so mark me brainleist

la parábola es el lugar

geométrico en el cual los puntos tienen una distancia idéntica, equidistantes,

de un punto denominado foco, f, y una recta denominada directriz

el radio vector de una

parábola es el segmento que existe entre un punto cualquiera y el foco.

por la ecuación se observa

que la parábola abre hacia la derecha, por lo cual podemos usar las siguientes fórmulas

la ecuación ordinaria de la

parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al

foco.

la fórmula de la directriz

es x + p = 0

resolviendo:

y^2-9x = 0

y^2 = 9x

4p = 9, entonces p = 9/4

entonces el foco tendrá la

coordenada f(9/4,0)

la directriz vendrá

expresada por

x + p = 0

x = -p

x = -9/4

el problema indica que la

ordenada es igual a 6, entonces

(6)^2=9x

x = 36/9

x = 4

entonces el punto al cual

hay que obtener la distancia será p(4,6)

calculando se tendrá: pf = 

pf = 6,25 u
