Two angles are congruent if and only if they have the same measure. write a definition based on the biconditional. a. two angles have the same measure. b. two angles are congruent. c. two angles are congruent if they have the same measure. d. if they have the same measure, then they are congruent.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

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)
