7x + 5.25 = 82.957x = 77.70X = 11.1
I believe that is the correct equation and answer. Hope this helped!

The evaluation is (2sin2∅-cos2∅)sec2∅.
<h3>What are trigonometric functions?</h3>
Trigonometric functions are functions used to relate the sides of a triangle with its angles.
Analysis:
2tan2∅ -(1- tan2∅)
2tan2∅ - 1 + tan2∅
3tan2∅ - 1
3() - 1
(3sin2∅/cos2∅) - 1
(3sin2∅ - cos2∅)/cos2∅
but 1/cos2∅ = sec2∅
(3sin2∅ - cos2∅)/sec2∅
