Z =
given W = XYZ
to isolate Z divide both sides by XY
= Z ⇒ Z =

Answer:
(X, Y, Z) = (-2, 3, 3)
Step-by-step explanation:
We can subtract the second equation from the first to get ...
Y -Z = 0
We can add the third equation to the first to get ...
Z = 3
Then ...
Y -3 = 0 ⇒ Y = 3
and ...
X -3 -2(3) = -11
X = -2 . . . . . . . . . add 9
The solution is ...
(X, Y, Z) = (-2, 3, 3)
Answer:
use a calculator du bro 56
Step-by-step explanation:
DECA=10, so a decagon has 10 sides.
the sum of all interior angles, in degrees, in a polygon is
180( n - 2 )
where n="number of sides".
for a decagon that'd be 180( 10 - 2 ).
