In the diagram, BD is a diameter and
21= 22. Explain why AB and CD have the same length.

Options:
A.) 1 and <2 are congruent vertical angles, therefore AB and CD have the same length.

B.)1 and <2 are congruent inscribed angles, therefore AB and CD have the same length.

C.)1 and <2 are congruent central angles, therefore AB and CD have the same length.

D.)1 and <2 are congruent alternate interior angles, therefore AB and CD have the same length.

Step-by-step explanation:

can U send figure please so that it will be more help ful

c

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
