Step-by-step explanation:
First, we should define supplementary angles.
Supplementary angles are angles that add up to 180 degrees.
Since 1 and 2 are supplementary and we know their values, we just set them equal to 180 degrees
(
4
y
+
7
)
+
(
9
y
+
4
)
=
180
Now just solve for one variable
13
y
+
11
=
180
13
y
=
169
y
=
13
Now the question asks for m<2, which is
9
y
+
4
So we just plug in
9
⋅
13
+
4
=
121
So m<2 is 121
