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

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10

true
