Answer 1

Answer:

6)

Given- AB=DB,AC=DC

find- X and y

solution- In∆ABC and ∆DBC

AB = DB (given)

AC = DC (given)

BC = BC (common)

∆ABC congruent to ∆DBC (by sss congruence condition)

angle ABC =angle DBC (by cpct) __ 1.

angle ACB = angle DCB ( by cpct) __ 2.

y+3=46° (from 1.). 35°= 2x+5 (from 2.)

y=46-3. 35-5 = 2x

y =43°. 30/2 =x

y= 43°. 15° =x
