Since the shown angles are equal, the shown segments inside triangle are bisectors of respective angles.
+----------------------------------------------------------------------+
| In any triangle, bisector of an angle divides the opposite side |
| in the ratio equal to the ratio of adjacent sides. |
+----------------------------------------------------------------------+
THEREFORE, in the given triangle
=
and y + z = 5.
So, the side of the length 5 is divided in the ratio 6:4.
It means that y =
=
= 3; z = 5-3 = 2.
Similarly, side of the length 6 is divided in propoprtion
=
.
So, the side of the length 6 is divided in the ratio 5:4.
It means that x =
=
=
= 3
, w = 6 - 3
= 2
.
ANSWER. x = 3
; y = 3; z = 2; w = 2
.
Solved.
