0.333 repeating is the answer :)
Since a plane is 180 degrees total, x=135
180-45=135
{ y = 4 - x
y = x - 4
Subsititute y = x - 4
[ ( x - 4 )] = 4 - x ]
isolate x for ( x - 4 ) = 4 - x
x = 4
For y = x - 4
Subsititute<span> x = 4
</span>
y = 4 - 4
y = 0
Solution
x = 4 and y = 0
hope this helps!
It is 30 degrees. Add 90 and 60 to get 180. Then subtract that from 180, since all triangles interior angles add to 180. You’ll get 30.
