Incomplete question. Not enough data.
In this problem, you there are only 2 different sets of measurements.
Angles 1, 2, 7, 8 are all the 30 degree angles. They are alternating interior angles of parallel lines cut by transverals.
Angles 3, 4, 5, 6 would be 150 degrees, because they are supplementary (add to 180) with the adjacent angles.
Answer: 4/a
Explanation:
(a+1/a)^2 - (a-1/a)^2
= (a^2 + 2a + 1)/a^2 - (a^2 - 2a + 1)/a^2
= (a^2 + 2a + 1 - a^2 + 2a - 1)/a^2
= 4a/a^2
= 4/a
