Answer:
140°
Step-by-step explanation:
<3 = 40 because they are vertical angles
<3 +<4 = 180 because they are same side interior angles
40 + <4 = 180
Subtract 40 from each side
40-40 + <4 = 180-40
<4 = 140
7
8+9=17 -10 = 7
You would substitute all x's with the number 30, so the answer would be f(30)=-1 or y=-1
