Cho tam giác ABC có AB=AC. Tia phân giác của góc A cắt BC ở D a) Chứng minh tam giác ABD = tam giác ACD
b) Chứng minh AD vuông góc với BC
c) Vẽ DH vuông góc với AB( H thuộc AB), DK vuông góc với AC( K thuộc AC)
Chứng minh DH=DK

i'm sorry i don't know

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
