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:
(- 1, - 6 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 270°
a point (x, y ) → (y, - x ), thus
(6, - 1 ) → (- 1, - 6 )
Answer:
-5/2
Step-by-step explanation:
i really hope this helps you out!
Original is 100
1/4 off is 25 off
75 left
10% what's left is 75-7.5=67.5
this was already out of 100
100=67.5=32.5
1/4 off and then 10% off is the same as 32.5% discount
