What do the measures of angles bda (90) and bea (90) and the fact that ad and ae are radii of circle a tell us about bd and be. i'd put a pic but i don't know how. sorry

BD = BE

Step-by-step explanation:

Given:

∠ BDA = 90°

∠ BEA = 90°

AD = AE = radii of circle A

We need to find measures of BD and BE.

Solution:

we know that BD and BE are tangents drawn from one external point B to Circle A.

Now by theorem which states that;

"When two tangents drawn to a Circle from one external point then their measures are said to be equal or we can say Tangents are equal."

So from above theorem we can say that;

BD = BE

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

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.
