Step-by-step explanation:
<u>Angles and Lines</u>
The figure shows two triangles WXZ and WYZ. Considering:
* Angles WXZ and WYZ are right (90°)
* Sides XW and YW are congruent (red marker on both)
* They share the side WZ.
We can conclude they are congruent. Thus, angles XZW and YZW are congruent or have the same measure:
5x + 4 = 6x
Subtracting 5x:
4 = x
Or, x =4
Thus:

Answer:
(x, y) = (3, 5)
Step-by-step explanation:
Equate the two expressions for y and solve for x.
x +2 = 2x -1
3 = x . . . . . . . . add 1-x
y = 3 +2 = 5 . . . . using the first equation
The solution is (x, y) = (3, 5).
