Find the measure of the missing angle.
2 answers:
That is a question about angles.
The first thing that we should to note is that a line do a straight angle. A straight angle is an 180° angle.
So, we can say that the sum of the angle <em>a</em> and the angle of 157° is equal to a straight angle. Let's make and solve a equation:
Therefore, the missing angle is 23°.

Answer:
Step-by-step explanation:
a.
y=0.75x
y-y1=(y2-y1)/(x2-x1)×(x-x1)
y-3=(6-3)/(8-4) (x-4)
y-3=3/4(x-4)
y-3=3/4 x-3
y=3/4 x-3+3
y=3/4 x
if y=f(x)
f(x)=0.75x
c.
f(12)=0.75×12=9$
