Actually Welcome to the Concept of the Angles.
Complementary angles are those which add up to get 90° , hence here
1.) 90-80 = 10° , 10 is complement of 80
2.) 90-(-120) = 210 , hence 210° is complement of -120
3.) 90-400 => 360°
4.) 90-95 = -5°
5.) 90-5 => 85°
6.) 90-(-35) = 125°
7.) 90-8 = 72°
all are the complement angles above.
I think it’s: Concurrency of Angle Bisectors of a Triangle.
No. It's rational. The solutions are +10 and -10.

Step-by-step explanation:
I got
44
and
5
Explanation:
Call the numbers
x
and
y
, you get:
x
+
y
=
49
x
=
8
y
+
4
substitute the second equation into the first:
8
y
+
4
+
y
=
49
9
y
=
45
y
=
45
9
=
5
so that:
x
=
8
⋅
5
+
4
=
44
