Answer:
Step-by-step explanation:
Take a triangle ABC, in which AB=AC.
Construct AP bisector of angle A meeting BC at P.
In ∆ABP and ∆ACP
AP=AP[common]
AB=AC[given]
angle BAP=angle CAP[by construction]
Therefore, ∆ABP congurent ∆ACP[S.A.S]
This implies, angle ABP=angleACP[C.P.C.T]
Answer:
The system of the equation has no solution
Step-by-step explanation:
Step: Solvey=3x+9for y:
y=3x+9
Step: Substitute3x+9foryiny=3x−4:
y=3x−4
3x+9=3x−4
3x+9+−3x=3x−4+−3x(Add -3x to both sides)
9=−4
9+−9=−4+−9(Add -9 to both sides)
0=−13
