Answer:
4x+x+15 = 180
5x+15=180
5x=180-15

Answer:If angles are complementary, then they are found adjacent to each other in a right angle.
From above, you can see that A+B=90
So I can add my two angles together and have it equal to 90
(
5
x
+
8
)
+
(
x
+
4
)
=
90
5
x
+
8
+
x
+
4
=
90
6
x
+
12
=
90
6
x
=
90
−
12
6
x
=
78
x
=
13
So
A
=
5
x
+
8
=
5
(
13
)
+
8
=
65
+
8
=
73
and
B
=
x
+
4
=
13
+
4
=
17
Just to make sure you are correct, add your A and B together and they should equal to 90
ie
A
+
B
=
73
+
17
=
90
