22.    what  is  an  equation  of  the  parabola  with  vertex  at  the  origin  and  focus  (−4,  0)? a.) x = 1/16y^2 b.) x = -1/16y^2 c.) y = -1/16x^2 d.) y = 1/16x^2

the answer is 2/54

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
