Isolate the a. Note the equal sign. What you do to one side, you do to the other.
Add 5 to both sides
-5 (+5) + 1/5a = 4 (+5)
1/5a = 9
Isolate the a. Multiply 5 to both sides
(5)(1/5)a = 9(5)
a = 9 x 5
a = 45
45 is your answer for a.

Answer:
276°
Step-by-step explanation:
In the figure attached, circle D is shown.
arc BA + arc AC + arc CB = 360°
(7n + 12) + (13n - 16) + 6n = 360
26n - 4 = 360
n = (360 + 4)/26 = 14°
arc BAC = arc BA + arc AC
arc BAC = (7n + 12) + (13n - 16)
arc BAC = 20n - 4
arc BAC = 20(14) - 4 = 276°
Answer:
The answer is 276 degrees. I checked on Khan Academy. The reason 84 degrees is NOT the answer is because that would be the minor arc, not the major arc.
