An exam worth 130 points has 32 questions. Each question is worth either 2 pt or 5 pt. You do all the 2 pt questions first to get them out of the way. Assuming you get all those 2 pt questions correct, how many of the 5 pt questions must you correctly answer in order to get at least 100 pt?

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.
