Answer:
(-1,4)
Step-by-step explanation:
Using elimination, add the two equations to get rid of the y variable.
17x = 43 - 15y
+8x = -68 + 15y
=25x = -25
<u>x = -1</u>
Now plug in -1 for x in any of the equations.
17(-1) = 43 - 15y
-17 = 43 - 15y
-60 = -15y
<u>y = 4</u>
Answer:
The triangles SYX and SYZ are congrient so by CPCTC
,
and
.
Step-by-step explanation:
Given information: YS is the perpendicular bisector of XYZ.
In triangle YXS and triangle YSZ,
(YS is the perpendicular bisector of XYZ)
(Common side, Reflexive property)
(YS is the perpendicular bisector of XYZ)
By ASA postulate,

The corresponding parts of congruent triangles are congruent. so,
