Answer:x=90 °
Step-by-step explanation:
In any circle the exterior angle formed is half of the major arc - minor arc .
Angle formed by tangents or secants = 
The sum of measure of arcs inany circle is 360°.
Minor arc is given as x°.So Major arc = 360-x.
Substituting the given values in the formula :


x=180-x
Adding x both sides we have:
2x=180.
Dividing both sides by 2.x= 90.

Answer:
y = 4x + 16
Step-by-step explanation:
y - 1 = 4(x + 3)
Has a slope of 4
y = 4x + c
32 = 4(4) + c
32 - 16 = c
c = 16
y = 4x + 16
