The perpendicular bisectors of AABC intersect at point
G. Find the length of BG.
B

= 9

Step-by-step explanation:

The given parameters are;

The point of intersection of the perpendicular bisectors of the sides , , and intersect (meet) at point G

Let D represent the point of intersection of the perpendicular bisector from G to , we have for ΔBGD and ΔCGD;

≅ by reflexive property

∠GDB = ∠GDC = 90° given that is the perpendicular bisector of

Similarly, ≅ , also given that   is the perpendicular bisector of

Therefore;

ΔBGD ≅ ΔCGD by Side-Angle-Side (SAS) rule of congruency

≅   by Congruent Parts of Congruent Triangles are Congruent, (CPCTC)

= = 9 by definition of congruency

∴ = 9.

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
