Answer:
WR ≅ WX
Step-by-step explanation:
To use the SAS postulate, you need congruent sides bounding a congruent angle.
Here, side WP is one side of one of the vertical angles, ∠PWR, so you need the other side of that angle: WR. The corresponding side in triangle VWX is WX. That is, for SAS, you need WR ≅ WX.
Q - r = r
Flip
r = Q - r
Add r to both sides
2r = Q
Divide both sides by 2
r = Q/2
Have an awesome day! :)
Answer:
No clue
Step-by-step explanation:
The solutions of x and y?
2x+y=8...(1)
x-2y=-1...(2)
for (2), x=-1+2y...(3)
sub(3) into(1),
2(-1+2y) +y=8
-2+4y+y=8
5y=10
y=2
sub y=2 into(3)
x=-1+2(2) =3
therefore, x=3,y=2
They are congruent because the angles are all the same for the one on the left the angles are 79° 43° and 58° and the triangle on the right the angles are 79° 43° and 58° you can say they are confident because of AA (Angle Angle) theorem which means that 2 angles are congruent which means both of the triangles are congruent.
