13 pi over 6 is equivalent to 390 degrees. This is a first quadrant degree angle. The reference angle is the supplementary angle of the angle given. The reference angle is equal to the didifferencef 3 pi and 13 pi over 6. This is equal to 5 pi over 6.
The polynomial is written in standard form and has three terms.
Answer:
a = 35
Step-by-step explanation:
5/7a = 25
multiply both sides by 7:
5a = 175
divide by 5:
a = 35
